Benjamin Rogue ePCP: Part 5
by Tom Gaylord, a.k.a. B.B. Pelletier
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.
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.
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.
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.
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 ([email protected]) 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.
