the only shot that should be off of your normal grouping is your first shot, and even then it shouldnt be that far off at 100 yards. this is called a cold bore shot. the fith shot or even 15th shot should not be off, unless you are shooting a high recoil rifle and you are flinching as you beging to get tired of the gun kicking your butt. Take a little break after shooting 3-5 shots, get up and walk around a little, and take a breather between shots.

What do you mean by "off" I have put 7 or 8 shots of .223 into a quarter at 100 yards. I know that no shocker but I'm just trying to understand what your asking.

I interpreted it as "how much does fouling affect accuracy after about five shots," but I'm not sure.

Depends which solvent, rust preventative/ oil and how you cleaned your barrel. For High Power Rifle Competition I like to coat the barrel with Break Free which reduces copper fouling when your shooting 50 to 300 rounds daily. The problem with Break Free, is the first round will be high and when you get to the 3rd round, it has settled down to zero.

Barrel bedding and heating of the barrel may make a big difference. So the only way to be sure is to go out and try it!

My Savage ML10 Muzzle Loader, I can shoot 70 shots easily without cleaning!

Barrel heating will cause more variation in your shot string than will fouling except in extreme instances. The more powder you are burning, the quicker the barrel heats up. Oil or solvent left in the bore will cause an erratic first shot (and sometimes higher pressures). That's why it is good to clean the bore after zeroing and fire one or two fouling shots followed by a clean dry patch or BoreSnake before hitting the field for the hunt.

it shouldn't be off at all unless the barrel gets heated up very quiclky like my .308 does. Then it might throw them off.

Could you get a little more detailed with your question?

Shouldnt be off group. I have put 30-40 rounds through my carbine and kept the pattern the whole time. Even better my old AR-15. I had 2 100 round mags. It would keep a decent group at the end of the second clip! What fun that was. I miss that gun!
