It’s taken me awhile to get back to this pistol because I injured my hand, so I couldn’t fill the Hatsan AT P1 PCP air pistol¬†from the hand pump for a couple of weeks, but last Friday I was at it again — probably for the last time. You may remember that I discovered that the AT P1 likes a fill pressure of 3,200 psi — which is sort of ironic in light of several recent reports I’ve done. This time, I used the Hill pump to fill the gun to that pressure to see if there are 10 good shots on a fill. That was the problem before — the circular clip holds 10 pellets, but the gun didn’t seem to want to shoot more than 7 of them on a single fill of air.

This test is being done because in Part 3, the accuracy test, I felt the scope I was using wasn’t giving the Hatsan AT P1 PCP air pistol the best chance for success. It was a vintage Weaver K856, which means a fixed 8x magnification with a 56mm objective lens. Though it doesn’t say anywhere on the scope, I’m pretty sure the scope’s parallax is fixed at 100 yards. At the 25 yards I was shooting, the target was slightly blurry.

The best group I got in that test was five Crosman Premiers into 0.678 inches at 25 yards. That was shooting off a sandbag rest with a rifle scope.

Today, we’ll look at the performance of the Hatsan AT P1 PCP air pistol for accuracy at 25 yards. It took a long time between this test and the last one because this gun is too loud to discharge inside the house. I had to do it for the velocity test and my ears are still ringing. I waited for a day at the range to test the gun for accuracy.

I mounted a vintage Weaver K-856 scope on the gun for this test. It’s a fixed 8x scope with a 56mm objective lens. I thought it would be clear enough at 25 yards (parallax set for 100 yards), but it turned out to be fuzzy. I will change scopes for the next test.

Today, I was all set to report the velocity of the .22-caliber Hatsan AT P1 PCP air pistol, when I discovered that there’s more I need to know about this airgun. I’d like to thank those who’ve been waiting patiently for this second report. I stalled for a long time because Hatsan uses a proprietary quick-fill probe. That means I have to undo one of my more universal fill connectors to attach their probe. Thankfully, the threads on their probe are standard 1/8″ BSPP that connect to most air hoses coming from tanks and hand pumps these days (I can still remember when that wasn’t true!), but I was working on both the Condor SS and the twist-rate report and needed a fill device for both of those. In the end, I pressed my Hill pump into service, and it proved to be a great way to fill the AT P1 pistol.

Update on some reports
Before I begin, here’s an update on a couple reports that you’re waiting for. I went to the outdoor range yesterday to shoot both the Walther LGV Olympia and the new New AirForce Condor SS at 50 yards. When I got there, the breeze was too much for the LGV, but I did try to shoot several groups with the Condor SS. I shot three 10-shot groups, waiting out the winds for every shot; but in the end, there was just too much wind to make the test a fair one.

One good thing did happen, however. I shot a certain .22-caliber heavyweight pellet that I haven’t tested before; and despite the wind, I got fairly good results. I’m going to save the pellet’s name for when I actually do the report, and I’ll also show you the group that I got.
