Re: AP20 POI low and inconsistent

Just to follow up on this, I sent the gun back to Umarex. Got it back about 10 days later and it now shoots great. No indication of what was wrong; the invoice just says "Repair Product" and "Adjusted velocity to 495 fps". No charge; it was under warranty.

AP20 POI low and inconsistent

I'm a new air gun shooter; the Hammerli AP20 is my first air gun. I've had it for a couple months with about 2000 rounds through it and it seems to be getting less accurate the more I shoot it. With the butt of the gun on sandbags, its point of impact is low and inconsistent (varies more than an inc...
