I have a Ruger P90 dc. That I love to shoot, I have noticed a slight decrease in accuracy since I bought it. I thought it was just that I had plateaued and at 62 that was as good as I was going to shoot. I've put 4-5000 rounds through the gun and it has been cleaned and oiled after every outing. There is a slight wear showing on the outside of the barrel where it moves in the slide. I just noticed when I went out with my son and his new XDm in 45 acp, that I was hitting closer groups with it even though it didn't feel quite as good in my hand(my hands are slightly larger than his) We were shooting at a coffee can at 50 yards. With his gun I went 5 for 5 but when I switched back to mine I went 2 for 5. I like to shoot at longer distances with my gun, 50-100 yards just for fun. Is it likely that this small amount of wear could be why my long range groups are opening up? ( just to piss of my son I like to place a 5 gal pail out at 100 yards could usually hit 5 out of 7 but now its moire like 3 out of 7) Thanks for any opinions.
Yes, same ammo. 200 gr hp, 5 grains tight group I load myself. Took a few weeks to dial in the round but it shoots very well in my gun. The only thing that has changed is the rounds through the gun, that said it is very possible that I have become complacent and am not trying to improve hard enough. That's why I asked. I don't mind getting a new barrel if that is it but don't want to do that if the problem is a loose nut behind the trigger, if you get what I mean.
