The new Rogue is simpler, more tractable.

Think of this report as a bonus. I thought I was finished with the Rogue after Part 4, but then Seth Rowland — the man who organizes the Malvern, AR, airgun show and also provides big bore airgunners with swaged and cast lead bullets — contacted me, saying that he had been following the series. He told me he had a couple different bullet designs, some that he swages and can control the weight and length of the bullet. He wondered if I wanted to test the rifle with some more bullets — this time from a source other than Crosman/Benjamin. He had no idea whether any of the bullets would work in the rifle, but he did know they were large enough to fit the bore well.

I thought, what the heck — let’s give them a try. I contacted Crosman to get an extension to the loan of the new Rogue. Since this gives me one more day at the range with the rifle, who am I to complain?

Seth sent me 5 bullets in all. They range from 89 grains to 137 grain, so the spectrum is covered pretty well. You may remember that I found the Rogue to shoot best with lighter-weight bullets, which is why Seth sent me these particular ones.

From the left, we have an 89-grain swaged bullet, 119-grain swaged bullet, 128-grain cast bullet, 130-grain cast bullet and a 137-grain swaged bullet.

At the range
The day was perfect. The wind was a light breeze that caused no problems at the 50-yard range. I took each bullet in succession, starting with the lightest weight and progressing to the heaviest. Each bullet shot a 5-shot group at 50 yards. The electronic valve setting was on Light for the bullet and Medium for the power. I figured that if any bullets showed promise, I could return and test them on High power later.

The 89-grain bullet had only fair accuracy and strung its shots vertically in a group measuring just under 4 inches. It was too early in the test to know very much, so I moved on to the 119-grain swaged bullet. It opened up to just over 5 inches, telling me this also was not a bullet for the Rogue. Since it was also swaged, I wondered if that was causing some kind of problem.

The next bullet was the 128-grain cast bullet. Five of those landed in 1.483 inches, looking very nice, indeed. That’s certainly minute-of-coyote or fox at 50 yards…and on out to, perhaps, 75 yards. The cast bullet looks like a design for either a black powder cartridge or a pistol. It was the best group I got so far.

Benjamin Rogue epcp big bore air rifle 128 grain cast bullet Medium power
Five shots with the 128-grain cast bullet on Medium power produced this group, which is under 1.5 inches.

Next came the 130-grain cast lead bullet, and it didn’t even land on the target paper. Since I back my targets with a 2-foot by 4-foot target paper to catch strays like this, and since I failed to catch this bullet anywhere, I stopped trying after three shots. Let’s call the 130-grain bullet a non-starter for the Rogue.

The last bullet was a 137-grain swaged design that also failed to make a hole on the large backer paper after 3 shots. It was out, as well.

So far
To this point, it looks like the 128-grain cast lead bullet is the one to spend time with. I chronographed it and found it averaged 699 f.p.s. on Medium power (138.91 foot-pounds) and 731 f.p.s. on High power (151.91 foot-pounds). On Medium power with a fresh 3,000 psi fill, the gun’s status panel tells me there are 11 shots at the beginning. But the status panel number of shots that remain decreases faster than the actual number of shots. Although it says there are 11 shots, there are really 6 or 7 shots before it’s time to fill again.

On High power, the gun starts out with 3 shots on the panel — but I found that I got only 2 shots before the gun wanted to be refilled. A third shot was possible, and I took one just to see where the bullet went. It stayed within the group, though on High power the group is larger than on Medium.

Five 128-grain bullets on High power opened up to 2.847 inches. The shot at the right is after a refill of air.

What do we know?
First, we know that cast bullets with grease grooves seem to shoot better in our Rogue than swaged bullets. At least, there’s an inclination in that direction.

Next, we know that the 128-grain bullet did best in this rifle. If further testing was to be done, that’s the bullet I would concentrate on. I went back and reviewed the performance with all the other bullets that were tested in the past, and this one looks quite similar to the Benjamin Pursuit 127-grain flat-nosed bullet. What that means is that it’s possible to cast your own bullets or to buy them from a source that casts them, as they’re going to perform similarly to the best bullets in this rifle. Both these bullets out-shot the 145-grain Nosler Ballistic Tips that are also good in the Rogue.

We also know that shooting on Medium power conserves air longer than High power, and the slight loss of velocity is inconsequential. Of course, I’d like to play with this bullet even more, shooting it with the control panel set to Heavy weight and shooting it on Discharge, as well as directly controlling the valve dwell time. From just what we have seen in today’s test, I would say this is a bullet to beat.

Remember — this was a test of unknown bullets to see if any were worth testing further. If I owned a Rogue, I would stock up on this 128-grain bullet and play with it more because I think this may be the best overall design for the rifle.

Thanks to Seth Rowland (sethrowland@att.net) for providing these bullets to test. He makes other calibers and will work with you to find the best bullet for your rifle.

Bottom line for the Rogue
The Rogue has its detractors — those who feel that it’s to advanced and expensive to be practical in the field. But those people disregard the fact that this rifle shoots as well as almost all other big bores of quality.

All I’ve done in this 5-part test is show you how it performs. The rest is up to you.

The new Rogue is simpler, more tractable.

After the last report, I spoke to Dennis Quackenbush about how the new Rogue I was testing. I explained that while it shot well with Benjamin bullets, it didn’t seem to group with cast bullets obtained from other sources. He first suggested that I try the old .38-caliber 200-grain lead bullet that we know as a police round here in the U.S.; but in the UK it was their substitute for the old .455 round. When they downsized their WWI service revolver to reduce the recoil, they substituted the 200-grain .38-cal. bullet for the much larger .455-caliber man-stopper they had in WWI. Unfortunately, they also knocked about 9 oz. off the weight of the revolver at the same time, with the result that the new cartridge and revolver kicked just about the same as the one it replaced. It was easier to carry, of course, and that’s always a consideration, but it wasn’t the man-stopper the older bullet had been.

I told Dennis that the heavier I went, the more the Rogue didn’t like the bullet, so he then came up with a different idea. He suggested I try a bullet with a different balance. He asked me if I had tried the rifle with a 148-grain .357-caliber wadcutter, which of course I hadn’t. Some wadcutter bullets have a hollow base that obturates when the cartridge explodes, thus filling the bore and sealing all gasses behind.

Benjamin Rogue epcp big bore air rifle wadcutter bullets
The .357 wadcutter bullet weighs 148 grains and has a hollow base similar to a diabolo pellet. That pushes the weight forward and helps stabilize the bullet in flight. This lead isn’t oxidizing. That white powder is the dry lubricant that has been applied to the bullet after casting or swaging. Notice the lack of conventional grease grooves.

The wadcutters were the first non-Benjamin bullets to perform well in the Rogue. They fed well, and they also shot to the same point of aim as both of the Benjamin bullets. This proves that a Rogue owner can cast his own bullets for the rifle and save a lot of money. In fact, with a Shoebox Compressor and casting your own bullets, the Rogue would be cheaper to shoot than a smallbore pellet rifle!

Low on air: What can I do?
When I shot the wadcutter bullets for accuracy, I knew my carbon fiber tank was running low. I still had to chronograph all the bullets at both power settings and wanted to save some air for that, so I decided to try something different during this group. Five bullets were fired with the rifle set to heavy bullets and medium power. That ran the gun out of a charge of air. The display panel said there were no shots remaining at that setting. I changed the power setting to discharge, which holds the valve open twice as long as normal. I then fired two more shots on the discharge setting just to see what would happen. I labeled each hole on the target, so you can see where every shot went.

The five bullets fired on medium power grouped in about 2-3/4 inches at 50 yards. Each shot is numbered. Then the two discharge shots hit lower and to the left. Interesting that you can actually get more shots on a fill than the status panel indicates!

Velocity
Now, it was time to test the velocity of all the bullets that were accurate in the Rogue. This exercise used up the remaining air in my tank, thus ending the day at the range.

Nosler 145-grain Ballistic Tip
The first bullet we’ll test is the 145-grain Nosler Ballistic Tip bullet that’s the best general bullet for the Rogue. On high power, the bullet averaged 774 f.p.s., with a range from 766 to 781 f.p.s. At the average velocity, the rifle generated 192.92 foot-pounds of muzzle energy.

On medium power, this bullet averaged 751 f.p.s. and ranged from 741 to 760 f.p.s. At the average velocity, the bullet generates 181.64 foot-pounds of energy. That’s pretty remarkable, because that’s also a good place to keep the power for the extra shots it provides.

Benjamin Pursuit 158-grain bullet
The Benjamin Pursuit 158-grain round nose bullet was tested next. It was tested in the last accuracy test and proved to be acceptable at 50 yards. On high power, this bullet averaged 741 f.p.s., with a velocity spread that ranged from 735 to 752 f.p.s. At the average velocity, it generates 192.69 foot-pounds of muzzle energy. The Nosler Ballistic Tip reigns supreme for power in the Rogue by a razor-thin margin.

On medium power, this bullet averaged 711 f.p.s. and ranged from 704 to 714 f.p.s. At the average velocity, it’s pumping out 177.4 foot-pounds of ebergy.

Benjamin Pursuit 127-grain flat-nosed bullet
The Benjamin Pursuit 127-grain flat nose bullet was the speed champ in the Rogue. On high power, it launched that accurate little bullet at an average 796 f.p.s., with a spread from 786 to 809 f.p.s. At the average velocity, this little pill produces 178.73 foot-pounds at the muzzle.

It’s the medium power setting that I’m interested in for this bullet, however, because I believe I would have a bullet mold made to cast this bullet if I owned a Rogue. At this setting, the bullet averaged 747 f.p.s., with a spread from 740 to 751 f.p.s. That’s 157.4 foot-pounds of muzzle energy, on average. That’s more muzzle energy than you get from a 40-grain high-speed .22 long rifle cartridge; and, of course, the larger .357-caliber bullet does far more damage. At that power level, the Rogue would be a good fox and coyote gun out to about 100 yards.

148-grain wadcutter
Finally, I did test the 148-grain wadcutters that Dennis Quackenbush sent me. I had only a total of 10 on hand, so I tested just one shot at each setting. On high power, the bullet went 757 f.p.s., which translates to 188.37 foot-pounds. On medium power, it went 732 f.p.s., which is 176.13 foot-pounds. It might interest you to know that the Rogue is propelling this bullet at very close to the same velocity that a .38 Special midrange wadcutter cartridge produces. If you turn the bullet around when you load it — so the hollow base faces forward — you’ve created a monster hollowpoint bullet. At close range, such a bullet has few equals for destructive capability.

General observations on the new Benjamin Rogue
In case you aren’t aware, I played a small part in the Rogue’s developement, so some will think I’m biased in favor of the gun. I assure you I’m not. But this test surprised me in a number of ways. The first was the velocity stablity the Crosman engineers have been able to build into the gun. No other big bore airgun comes anywhere close to what the Rogue can do, as far as maintaining velocity with a specific bullet.

The magazine feeding problem is now gone. As long as the bullet is sized to enter the bore, it will feed fluidly through the redesigned magazine.

Accuracy has been improved. The 145-grain Nosler Ballistic Tip is still the best bullet overall, but the 127-grain Benjamin Pursuit is more accurate and more fun to shoot. If you own a Rogue, you might think about having a bullet mold made up to cast this bullet in soft lead. I hear that Mr. Hollowpoint also has some bullets that do well in the Rogue. After testing some in my .308 Quackenbush, I believe it.

The trigger is greatly improved. That was the part that Lloyd Sykes and I were worried about with the original Rogue. Well, Crosman has done it right, and I know hunters will like this one.

As far as worrying about whether a new Rogue you buy is a real new one or just one that’s left over I will say this. Crosman went to extreme lengths to remove all unsold Rogues from their dealers long before they released this new model. I’m sure those guns were reworked to the new standard. So, unless you’re buying from a hobby dealer (someone who isn’t really doing it as a business) or out the back of a car trunk, I would say you’re going to get the newer design.

I would like to thank the Crosman Corporation for providing the new Rogue for this extensive test.

The new Rogue is simpler, more tractable.

Thank you for being so patient with me on this report! I was testing the Benjamin Rogue .357-caliber big bore rifle all month long, but I had nothing to report until now.

I go to the rifle range almost every week these days. I often have at least one airgun to test, and I also find that shooting firearms keeps my mind fresh so I can address airgun questions better. Plus, I just like to shoot and since this is my job — why not?

The first time I took the Rogue to the range I was trying three different styles of cast lead bullets that had been supplied to me when I reviewed it for you earlier. Crosman had sent two of them, and Mac gave me the third when he heard what I was testing. I never lubricate lead bullets that I shoot in big bore air rifles, so I took all three of these bullets to the range as they were cast. You need to know that, when a bullet is cast, it comes from the mold not perfectly cylindrical. In black powder arms, where I also shoot lead bullets as-cast but lubricated, the bore will make them round; and in so doing, they seal the bore better. The guns I shoot are all vintage arms with bores much larger than today’s guns of the same caliber — so it’s become a habit of mine to shoot bullets as-cast.

Benjamin Rogue epcp big bore air rifle three cast lead bullets
I first tried these three cast bullets in the Rogue. On the left is a 150-grain flat-point. The middle is a 156-grain semi-wadcutter. The dark bullet on the right is Remington’s 158-grain swaged bullet that’s been tumble-lubed in graphite. None of these worked well in the Rogue.

But I couldn’t get any of these bullets to feed into the Rogue at the range! They were all too big. So, that day was a bust. I did shoot a few Nosler Ballistic Tips, but we already know how accurate they are, so I didn’t bother reporting on that trip to the range.

When I returned home, I called Crosman and spoke to Ed Schultz — their head engineer. I told him that I thought they needed to cut a leade (a tapered entrance) into the breech so these larger bullets would fit. Ed told me that, in fact, they had cut a leade in the rifling — and they’re cutting what amounts to a bullet-sized chamber in the breech. The bullets I was feeding the rifle must have been larger than 0.359 inches in diameter. Well, of course they are, because cast lead bullets are never perfectly cylindrical until you size them. I hadn’t sized these bullets, so of course they were causing feeding problems. Problem solved!

The next time I went to the range, I took the same three bullets, and all were sized to 0.359 inches. That made all the difference! Now, they fed perfectly through the magazine and into the breech. But none of them were accurate. The best I was able to do was one 5-shot group of about 7 inches. But the average group was closer to 12 inches. And that’s at 50 yards off a rest. There was still nothing good to report.

I returned home and called Ed Schultz, again, to ask if the Rogue could handle any bullet other than the Nosler. The first time I tested the gun, I had success with a light bullet of less than 100 grains, but I was out of those and didn’t know where to get more. I hoped Ed would have an answer, and he did. He said they’d been having success with their Benjamin Pursuit 158-grain round-nosed bullet and their Benjamin Pursuit 127-grain flat-nosed bullet, and he said he would send me samples of each to test.

Benjamin Rogue epcp big bore air rifle two lead Benjamin Pursuit bullets
Two Benjamin Pursuit lead bullets for the Rogue. On the left is the 127-grain flat point, and on the right is the 158-grain round-nose.

Last week I went to the range with both new bullets and tested the Rogue with each. The results were very encouraging, and that’s what we’ll look at today! Let’s look at the 158-grain bullet first. This is a blunt-nosed lead bullet that mimics the old .38 Special 200-grain police revolver round, but is shorter. It comes unlubricated in a box of 50 and is a cast bullet with a beveled base for easier reloading. So somewhere there is a mold for this, or one can be made, if you cast your own as I do.

The bullet fed without a fault through the magazine, and I was surprised that it shot to the same general point of aim as the Nosler. Only a few clicks of elevation were required to get it printing where I wanted it. I selected the heavy bullet weight and the medium power level on the gun’s control panel to conserve air more than anything. The readout said that with 3,000 psi I had 7 good shots in the gun; but when I fired, that number dropped to 4…and then to 2. Instead of 7 shots, I got just 3 — but at least I knew exactly where the reservoir was at all times.

I decided to shoot 10-shot groups this time, so I shot 3 and refilled, and so on. For the final 4 shots, I shot past the low-air warning because I’d been told by Crosman that the gun was now keeping even the first couple of those shots within 30 f.p.s. of the average. The new software doesn’t allow as much variety of choices for bullet weight and power, but it controls the shot-to-shot consistency much closer. You give up some shots per fill, but you gain accuracy, as you will see.

Ten 158-grain Benjamin Pursuit round-nosed bullets made this 2.587-inch group at 50 yards. That’s minute of coyote out at 80 yards.

Next, I tried the 127-grain flat-nosed bullet. For this one, I set the control at light for the bullet weight and medium for the power. The panel told me there were 11 shots at 3,000 psi, and I actually got 9. This time, the bullets all seemed to got to the same place on the target. What a wonderful little bullet this is for the Rogue!

Ten 127-grain Benjamin Pursuit flat-pointsd went into this 1.835-inch group. This is the bullet for this rifle! There are four bullets in what looks like a string of three at the top right of the group and two in the X-ring.

The readout on the last two shots with the 127-grain bullet. Notice the air pressure remaining. The readout disagreed with the gauge on my tank by 300 psi, but it was very accurate for controlling the gun.

I noticed while shooting the lighter bullet that the gun readout didn’t agree with the gauge on my air tank. It was off by 300 psi, yet it worked perfectly for the gun. So, I just paid attention to the gun readout, but filled using the gauge on my tank.

The trigger
I’d forgotten just how nice the new trigger is, but I have to say — Crosman got it right. It’s light, crisp and releases with no undue movement to the rifle. It feels like a mechanical trigger though I know it’s electronic. I do hope Crosman will put this trigger on other air rifles in the future, as I know you would all enjoy it.

Where we are
This test turned out to be a very pleasant surprise for me. After those times at the range when nothing went right, it was a surprise to learn that the new Rogue is a better shooter than it was in the first iteration. True, it doesn’t get as many shots per fill, but those shots it does get are all so stable that I don’t see how you could complain.

I still need to chrongraph the rifle with the two new bullets, plus I would like to see how it performs at high power. The reason I didn’t do that on this trip is because I know there isn’t that great a velocity difference between the two settings. But I still want to test it. So, we’re not done with the Rogue just yet.
