We’re certainly getting a good look at the Benjamin Trail NP pistol! While the title says this is Part 6, it’s actually the 7th report because Part 4 was so large it had to be broken into two parts.
Let’s look at the performance of the pistol after break-in. This test pistol has been shot so much that it’s now broken in, so today we’ll look at the velocity. Crosman says in the owner’s manual that the pistol needs several hundred shots before it’s fully broken-in, and this gun certainly has that many shots through it.
They also say the gun will become quieter after a break-in, and the test pistol is certainly quiet now. Apparently, some guns have detonated and surprised their owners, so Crosman is being conservative in its explanation. The test Trail NP pistol has never been very noisy.
I’ll report the velocity of each pellet before and after the break-in period, so you can compare them.
The first pellet I tested was the 7-grain RWS Hobby. It’s normally the fastest lead pellet in almost any airgun.
Crosman SSP hollowpoint
The Crosman SSP hollowpoint is a 4-grain, lead-free pellet that’s shaped like a wadcutter but with a deep hollow point. Being so light, it’s a real speed demon.
Crosman Powershot Penetrators
Crosman Powershot Penetrators are synthetic-jacketed pellets that have a metal core. They weigh 5.4 grains and loosely fit the bore of the Trail NP pistol.
Crosman SSP pointed
Crosman’s SSP pointed pellet is another 4-grain, lead-free pellet. You’d expect it to have about the same performance as the SSP hollowpoints, but this pellet isn’t sized as well as the hollowpoint. Consequently, they fit the bore variably, which affects the velocity.
JSB Exact RS dome
The last pellet I tried was the JSB Exact RS dome. It weighs 7.3 grains and fits the bore loosely.
So there you have it. All 5 of the pellets shot slower after the break-in, and all but one had more consistent velocity spreads. Clearly the Benjamin Trail NP pistol does break in as the company states in the owner’s manual.
This report has been a look into the performance of a spring-piston air pistol as it breaks in. We’ve seen the way to maximize the accuracy of the airgun, and we’ve learned how to overcome the too-tall front sight post. I hope this experience has been of benefit to the new shooters and perhaps provides a template of how a spring gun breaks in.
