- Additional testing
Today we look at the accuracy of the Benjamin Trail Nitro Piston Mark II with the factory-mounted open sights. But before we get to that, there is some old business to clear up.
There was quite a bit of interest in the adjustable trigger last time — mostly because I showed that I could not get a screwdriver on it to adjust. There was so much interest that I vowed to try to adjust it for this report.
I removed the barreled action from the stock. All it took was removing the 4 stock screws and lifting the action out of the grip/stock. The safety button fell out at the same time.
Then I set about trying to adjust the trigger, which is done via one screw behind the trigger blade. That screw can lengthen or shorten the length of pull of the single stage. Alas, it was already adjusted as far as it would go, so the whole drill was for naught. As long as the trigger pull is right now, I sure didn’t want to add any length to it!
With the pistol assembled again I began the test. I shot from a sandbag rest at 10 meters. The Trail NP Mark II is so heavy that I rested the bottom of the grip on the bag to help support the weight. I fired 5 shots with each of four pellets. The cocking assist remained on the barrel for all shots.
Then I did some additional testing that I will describe when we get to it. Let’s go!
The pistol was hitting about 6 inches low when I first shot with 7.9-grain Premier lites. That’s with the cocking assist installed, which is the way I think they want you to shoot it.
The sights adjusted up well and I was able to get on target in 6 sight-in rounds. The first group measured 1.018-inches between centers at 10 meters. All the pellets landed on target, with 4 of them in the black.
I was actually surprised by this first group. It was better than I had expected.
I wondered how well I would be able to shoot with the sights, when the front sight is wider than the rear notch. The answer is — not very well. I will say more about that at the end of the report.
Next I tried RWS Hobby wadcutters. They fit the breech snugly and that gave me confidence they might do well. Five went into 1.045-inches at 10 meters, with four of them in 0.588-inches. This showed promise!
Air Arms Falcon
Next I tried Air Arms Falcon pellets. These gave me the best group of the test — 5 in 1.02-inches at 10 meters with 4 in 0.277-inches. I found that astounding! It was worthy of additional testing.
Qiang Yuan Training pellets
The last pellet I tested was the Qiang Yuan Training pellet. These wadcutters are heavier than Hobbys and often prove very accurate in guns. Not this time, though. Five went into 1.224-inches at 10 meters, which was the worst group of the test.
Someone wanted to know how the pistol groups with the cocking aid off, so that was next. I used the Falcon pellets that had proven most accurate and I shot at a top bull on the target. All my shots went many inches higher, missing the pellet trap and shooting a huge hole in the plastic leg of my storage shelf where the pellet trap sits. They then embedded in my garage drywall.
I was so ticked off that I didn’t adjust the sights and try again. I should have, but I was angry at the damage. I should have looked through the spotting scope before firing all 5 shots, and that omission made me even angrier!
So, that question hasn’t been answered yet. But I did replace the cocking aid and fire a final group of the Falcon pellets with the aid installed. This time 5 pellets went into a group that measures 0.868-inches between centers. It’s better overall than the first group, but lacks the tight cluster of 4.
The groups of Hobbys and Falcons lead me to believe that if I were able to aim this pistol better the groups would be smaller. I think I need to test that. The front sight is so fat that its sides are wider than the rear notch. I know I am supposed to be using the fiberoptic dots, but they aren’t good for much more than tin-can plinking.
I originally thought of mounting a pistol scope on the gun, but a reader’s comment reminded me that I own several dot sights that might be perfect. I will try one of them. There will be at least one more report, and at that time I will test the pistol with the cocking aid removed for each shot.
Cocking the pistol is still easy and the firing cycle is smooth. The trigger does have some creep, but it’s not bad.
The Trail NP II pistol is doing better than I thought it would. I was surprised to see that I could keep most of the pellets in the black at 10 meters.
The trigger should not be considered adjustable. Just learn to live with it the way it comes from the box. After examining it for this report I don’t think there is an easy way to make it any better.
