This report covers:

• Assembly
• Lubrication
• Testing the rifle
• Crosman Premier lite pellets
• Air Arms Falcon pellets
• Evaluation to this point

Today, I’ll finish the tune of the Feinwerkbau Sport air rifle, and then we’ll test it. When we ended the last report, we had looked at all the parts and cleaned off the excess gear oil.

Assembly
Now it’s time to assemble the rifle. I looked at the trigger assembly that receives and holds the piston rod when the rifle is cocked. It’s very similar to the 124 trigger, but I can see refinement in fit and finish. This won’t be an easy trigger to modify, but it’s so nice as it comes from the factory that this isn’t an issue. I did not lubricate the trigger before assembly, but I did dry off the gear oil.

This report covers:

• Disassembling the Sport
• Spring guide was loose
• Remove the piston
• Piston comes out
• Mainspring tube/compression chamber finish

Okay, today the Feinwerkbau Sport air rifle comes apart, and we’ll start looking inside. This report is huge, so it will take today and tomorrow to complete.

Some of you might like to compare what you see in the Sport to the FWB 124. That can be seen in the 15-part report I did on the FWB 124.

Okay, enough explanation. This is what you’ve been waiting for, so let’s get to it!

Benjamin Marauder .177.

Today, I’m doing an accuracy test of the .177-caliber Benjamin Marauder at 50 yards because I forgot to do it when we were looking at that rifle back in the summer of 2013. I’m inserting it in between the tests of the .22-caliber Benjamin Marauder with synthetic stock and will go back and make a notation in the original Part 6 of the .177 rifle test that alerts readers to this omission and links to this test. The next report after this will be the first accuracy test of the synthetic-stocked Marauder. I apologize for any confusion this has caused, but I didn’t want to overlook this test.

This report is an emotional one for me. The last time I tried to report on the .25-caliber Benjamin Marauder, I became very ill and it took me two years to complete the test. In fact, I never did complete the test myself because I was in the hospital part of the time. My buddy, Mac, drove from his home in Maryland to Texas to test airguns for me so he could bank a lot of data and pictures that allowed me to write my blogs from a hospital bed. Mac is now gone, and I’m starting all over again with this rifle.

Today, we’ll adjust the Benjamin Marauder PCP air rifle to accept a lower maximum fill pressure and still deliver about the same velocity as before. Before we get into the report, let’s consider for a moment what we’re about to do. As far as I know, the Marauder is the only PCP on the market that allows this kind of adjustment to be made. A great many PCPs have adjustable power, and indeed, the Marauder’s adjustment process for power has been sharply criticized on the internet…mostly by people who don’t appreciate how it works in conjunction with this other adjustment that’s unique to this rifle.

Today, I’m going to attempt to correct the accuracy problem I created in the last report, where I reduced the average velocity from 1015 f.p.s. to 886 f.p.s. in the Benjamin Marauder while testing with Crosman Premier 7.9-grain pellets. The best group at the higher speed was 10 shots in 0.285 inches, center to center, at 25 yards; but at the new lower velocity, the best group was only 0.397 inches between centers. I was hoping to get approximately the same group size — around 10 shots into 0.30 inches at 25 yards at the lower velocity. When that didn’t happen, I had a decision to make. Should I continue with the other things I wanted to do, or should I fix this one first? I decided to do what I would have done had I not been testing the rifle for a blog, but just for myself. I decided to get the accuracy back on line.

Before I begin today’s report, I have some news about Leapers’ scopes for blog reader Kevin. He wondered what the status was on the new Bug Buster scopes with the thinner reticle lines, so I asked Leapers for an update on that plus a couple other scopes that will be coming out soon. The new Bug Buster is apparently coming to market very soon. It’s impossible to say for sure exactly when, but the next 60 days sounds about right. Leapers will be sending me a sample to test for you, so I’ll do a report on it. But I also learned that they have several full-sized scopes that have parallax correction down to 5 yards. That’s almost in the Bug Buster range. They’re sending me some samples right now, and I’ll report on them for you.
