So do you run a patch through the bore periodically as you shoot 100rnds? LolRunning ammo through a dirty barrel can lead to scarring and decrease in accuracy. If you can’t hit the broad side of a barn anyway it doesn’t matter.
I don’t let my guns get super dirty or anything. I keep an eye on the bore.
Maybe you’re right for competition shooting. But for casual plinking at 25 yds I think I’m accurate enough on a barrel with a few hundred rounds through it. I dunno maybe I’m crazy haha
