Wow! More than one month has passed since the last part of this report. I’ve been to the Roanoke airgun show and also out to the rifle range at least 3 times trying to get the data for today’s report, but what a quest it has been! It all boiled down to false confidence in my ability to get the job done. I’m used to certain rifles cooperating with me every step of the way, and this time I got called by the fates who expose pride for what it is.
I’m not going to bore you with all the details, but I will point out the most recent example of my stupidity because it’s a lesson for us all. When I went to the range last week, I thought I was ready to complete my 50-yard test of the .25-caliber Benjamin Marauder. I’d swapped the scope mounts from a previous test because they were too high. The new mounts were lower, and I didn’t have to hold my head as high on the comb. I knew this would help with the accuracy. But then I went to the Roanoke airgun show, and forgot that I’d made this change.
What’s most important about the change, though, are that the new mounts were vintage B-Square adjustable mounts. And the rear ring was jacked up higher than the front. I always liked that setup because it gets the drooper problem taken care of on the first shot — even if there isn’t one! But not if you forget that you did it!
And that’s why this report didn’t happen last week. I had the Marauder at the range with the TX200 Mark III, on which I reported last weekWhen I shot the Marauder, there wasn’t a pellet hole on the paper. And I’m not just talking about the target paper, either. I mean the 2-foot x 4-foot backer paper that I use whenever I have a rifle that’s not known to be sighted-in.
Naturally, I was disappointed. This was a Marauder after all, and I expected it to go right to the point of aim. After shooting just two 8-round magazines, I took the rifle off the line and put it away. I needed to look into the situation deeper and figure out what was wrong.
What was wrong, was that I had forgotten about the new scope mounts. When I looked at the scope back in my office, I immediately saw that the rear was higher than the front. Then I vaguely remembered something about changing the mounts before going to the Roanoke airgun show, so I reread the last report and discovered what had happened. The gun had not been sighted-in with the new mounts. It was obvious that the scope was set up for a rifle with severe barrel droop, and this rifle doesn’t have that.
I even went back to the rifle range last Friday and looked at the backer board where my target and backer paper had been stapled. Sure enough, above where the top of the paper had been there was a hole in the backer board. It had the appearance of a nice rifle group. And some of the holes in the group appeared to be .25 caliber.
Suspecting what happened, I started shooting at an aim point much lower than my anticipated target. Sure enough, my pellet was hitting the paper about 16 inches high and 6 inches to the left. That’s a problem I can deal with! All I had to do was adjust the scope down and to the right, and I was on target. It took me less than 10 minutes to get my groups landing where I wanted at 50 yards. Now, it was time to test the rifle.
The first group was shot with H&N Baracuda pellets. In the past, these were the most accurate .25-caliber pellets on the market, but they have since been replaced by several others, including one huge surprise that emerged in this test! The group measured 1.021 inches between centers. It’s a good group for any rifle at 50 yards, but I did think the Marauder might be capable of better.
I should mention that I was firing two magazines of eight shots each in this test. So the groups that you see have 8 pellets and not 10 in them. I recharged the rifle with air after every 16 shots because the reservoir pressure had dropped to around 2,100 psi by that point. That was as low as I felt it could go and still be accurate.
JSB Exact King
The next pellet I tried was the JSB Exact King, a .25-caliber pellet that’s shown a lot of promise in recent testing. The first group I shot measured 1.447 inches between centers. That’s not very good for a PCP rifle at 50 yards. Interestingly, however, 7 of those 8 shots went onto 0.719 inches, and that is good. I hoped that the one flyer was an anomaly, and that a retest of the same pellet would do better.
The second group of JSP Exact Kings when into 1.094 inches. That’s a lot better, but it still wasn’t what I’d hoped for, so I left the Kings to try other pellets.
Another stunning pellet in .25 caliber is the Benjamin dome. It has no model name, but you could think of it as a Premier pellet because it looks similar to the other pellets in the Premier line. The first group of 8 pellets measured 1.226 inches between centers, which was again larger than I was looking for.
The second group of Benjamin domes measures 1.06 inches. While that’s better, I still thought the rifle could do more.
The last pellet I tried was the .25 caliber Predator Polymag. It showed well in the 25-yard test and earned its place in this test. There really aren’t a lot of options when it comes to accurate .25-caliber pellets, and I think we’ve included all of them in this test. Yes, there are other brands out there, but do they perform? In my experience, they don’t.
The Predator is a hollowpoint pellet that has a red plastic tip in the center of the nose. Normally, hollowpoints fall off in accuracy at around 25 yards, but this pellet doesn’t. That tip seems to do its job.
The first group of Predators measures 1.121 inches between centers. Once again, that’s okay for 50 yards, but it’s nothing to scream about. But the second group measures 0.808 inches between centers. That’s what I was looking for! While the Marauder can’t be expected to shoot that well every time, this group proves that it has the potential. And it does it with a pellet that is acknowledged to be a great hunting pellet!
No .25-caliber airgun has ever been as accurate as the best .22 or .177 guns. What we see from this test is a range of results that represents what the .25-caliber Benjamin Marauder can do at 50 yards. I think these groups show what this gun can do very well. Sure, if you shoot more there will be some smaller groups. But there will also be many more groups that are larger than those shown here. I think we can safely say the Marauder in .25 caliber is capable of putting 8 shots into one inch at 50 yards when you do your part.
The .25-caliber rifle uses a lot of air! I was getting just 16 good shots in this test on a 3,000 psi fill. Compare that to the 32 good shots I got in the test of the .177-caliber rifle filled to the same pressure.
From a handling standpoint, there isn’t a nickel’s worth of difference between the .177- and .25-caliber rifles. The trigger can be adjusted to operate virtually the same, and the stocks feel the same. The one small difference is the .25-caliber gun does move back slightly with each shot. I didn’t feel that with the .177, but I definitely felt it in this test.
If you want a .25-caliber hunting air rifle, I think the Marauder is a good candidate for your short list. It’s powerful, accurate, quiet and reliable. How much more can you ask?
