I received a 25 cal this past Saturday and have shot about 400 rounds through it. I'm unable to get good groups with it. 3 inches at 50 yds, 5 inches at 100 yds. I have cleaned the barrel twice and reattached the scope. The only thing I can find wrong is two skid marks inside the end cap ,nothing on the baffles. I have no mods to it and only adjusted the velocity screw. If a pellet is hitting the end cap the pellet is already unstable. I shoot from 2800psi to 2600 psi and that only gives me 7 shots but the standard deviation is 1.4 - 2.5 I only shoot seven because of the low SD and since I'm using the Benjamin hand pump and it only takes 30 pumps to get it back to 2800. I'm 58 and 150 pounds so I don't want to pump anymore than 30 at a time. Two or three of the seven shots will be at the bulls eye but the other three or four will be flyer's two or three inches away. Even the flyer's have the same velocity as the ones that hit the bull so I don't think the flyer's are due to hitting the end cap.I'm shooting JSB Exact 24.4, Benjamin 27.8 and H & N Barracuda 31.0. After shooting about 300 pellets I was able to focus enough that I can see the pellets going from my gun to the target and I can see the flyer's cork screwing and curving to the target ,the ones that hit the bulls eye I can't see because the cross hairs block my view. When I cleaned the barrel the tight patch went through the barrel very smooth and no lead on the patch. I shoot a lot of lead cartridge guns so I can tell lead in barrels and this barrel felt clean and smooth. I called Crossman and they were very nice and said I could return the gun or they would send me a new barrel but I would like to see if anyone else has had this problem. With about 1800 pumps on this hand pump in three days I'm tired and sore. If anybody is interested in making a cheap backstop I'm using a cardboard box filled with dirt and I use a hand dolly to move it to my different yardages. The box was originally 5 inches deep but when I added dirt it bulged in the center. I have had no pellets penetrate with 400 rounds so far and I just tape targets on top of one another so the dirt stays in. When the box gets bad I'll use another box.
