Benjamin Trail Nitro Piston 2
Benjamin Trail Nitro Piston 2

This is accuracy day with the second Benjamin Trail Nitro Piston 2 rifle — the one Crosman sent especially for this test. We’ve already seen how this second rifle exceeds the power of the first one, so today we’ll see what impact that has on accuracy. As with the first rifle, I’ll shoot 14.3-grain Crosman Premier pellets exclusively in this test.

Rifle was set up
When I unboxed the scope, I found the rings already installed in the correct location, meaning I could install them directly on the rifle. That proves this rifle has been tested and set up before I received it. The scope went on quickly, and I found it was very close to being sighted-in; but the inability to focus the target as close as 25 yards was a hinderance to aiming. I estimate my groups were a quarter-inch larger than they needed to be because I couldn’t see well enough to put the crosshairs on an exact spot. The scope arrived set at 4X, which indicates the rifle was tested at 10 meters or yards before it was sent. At 25 yards, I wanted to see the bull more clearly, so I adjusted it to 9X. But as I said, the focus was off because the scope is parallax-adjusted for a longer distance.

The hold
I refined the sight setting and proceeded to test the hold I thought would do best — based on results from the first rifle’s test. I also tried several other holds and hand placements, establishing one thing for certain. The NP2 wants to be held firmly. Do not use the artillery hold. Instead, I found it best to slide my off hand out to almost the end of the stock and grip the forearm firmly. I can feel the forearm screw holds on the tips of my thumb and fingers, so I know my hand is in the same place every time. Any hold that wasn’t firm allowed pellets to rise vertically. I fired probably 30 shots testing just the different holds and pressures.

When I used the classic artillery hold, this is what I got at 25 yards — every time! They’re all in line but off vertically. The NP2 wants to be held firmly.

Accuracy
I then shot three 10-shot groups using the factory scope. The best of them measures 1.104 inches between centers, and the worst measures 1.168 inches. I really tried to do well, but the blurriness of the target did cause my aim to be off.

Benjamin Trail Nitro Piston 2 best factory scope group
The best 25-yard group using the factory scope and the best hold measures 1.104 inches between centers. No, I didn’t get the images mixed up. This group is slightly smaller than the one below.

Benjamin Trail Nitro Piston 2 worst factory scope group
The worst group with the factory scope isn’t much different than the best. Ten Premiers went into 1.168 inches at 25 yards.

I felt the factory scope was hindering my best efforts, so I swapped it for an older CenterPoint 3-9X40 with an adjustable objective. This scope is one CenterPoint no longer carries. It’s a simple scope without an illuminated reticle; and other than the larger objective lens and the AO, it’s close to the scope that came with the rifle.

I allowed a day to pass between the first shooting session and the second because too much concentration makes me lose my edge. The next day, I shot another four 10-shot groups, plus some more sighters to get the scope shooting where I wanted. On this second day, my groups ranged from 0.895 inches between centers to 1.483 inches. I learned as I went, refining the hold that seems to be critical with the NP2. The worst group, for example, came when I experimented with the firmness of the offhand grip.

By the end of the session, I knew what this rifle wants — a firm hold of the off hand as far out on the forearm as you can comfortably hold and a firm hold of the pistol grip. Pull the butt into your shoulder firmly. This is not a death grip — just a firm hold, and it seems to be what the NP2 wants.

The best group with the second scope measures 0.895 inches between centers at 25 yards. The second-best group was almost the same size as this.

Benjamin Trail Nitro Piston 2 worst new scope group
The worst group with the second scope measures 1.483 inches between centers at 25 yards. I was experimenting with the firmness of my grasp during this group.

I’m not through with this rifle, yet. Each one of my second-session groups contains a large cluster of shots that are very close, then some strays that wander off — usually down, but not always. I think I’m close to understanding what this rifle wants, but I’m not there yet. I think it needs a very repeatable offhand grasping pressure. I’ll give it one more session and also shoot some different pellets next time — to see if I have been missing anything by shooting Crosman Premiers exclusively.

A hunter’s rifle
I have seen rifles like the NP2 before. They take some getting used to, but they reward the shooter with incredible accuracy once their secrets are learned. They’re rifles for hunters who use only a single rifle for all their needs. For the price this air rifle costs, I don’t think you can get one that’s any better.

Comparison with the first rifle
The first NP2 also took getting used to; but when I did, it gave me a best 25-yard group of 0.704 inches at 25 yards. So far, this rifle has given a best of 0.895 inches. Both rifles seem to want to do better, but I haven’t discovered quite how, just yet.
