[QUOTE="HunterGreen, post: 1138006, member: 76185"] Bigeclipse, it's a proven fact, glad you now know the reason. Next time you hit the range, (I can't over state this) record your first clean cold bore shot. You must take your first shot as if the world depended on that shot pretend that you can change the course of history with that first shot. Now shoot three to five shots let the barrel cool down and note where these shots are impacting. Keep shooting at least 20 rounds between cool-down periods and note their POI. Wrap it session, apply moist cloth with hoppies cleaner and (JAG) not brush, run it down (1) time, let it sit till you get home and run dry patches. (Note, this will not remove copper, only powder residue that traps moisture and cause rust). Next day if possible, take your first copper fouled cold bore shot like the world depended on it. Now you can pause and admire your exact point of impact has not changed. The only time your point of impact will change is with these two situations, shoot at least 20 rounds rapidly but accurately and notice if your groups maintain size or open up. secondly, accuracy will be limited because copper fouling will eventually put resistance on your bullet down the barrel flight path, this well increase pressure and your velocity will decrease between 22-70 or more feet per second and your groups will open up, at that point you must remove some copper out.
