My daughter and I have been enjoying our MKIII's at the range lately and I have noticed what I consider to be a severe lead fouling problem. Hers is a 5.5" bull barrel 22/45 and mine is a standard 5.5" bull barrel MKIII. We are going for accuracy so I tried out the Remington .22 target ammo. We have had pretty decent results so far with accuracy and in 1000 rounds have had no misfires. The issue is with the fouling. After only 300 rounds the barrels are so fouled it begins to affect accuracy and can be seen with a bore light. I am new to rimfire pistol shooting so I am unsure if this is a common problem or if this is the ammo causing this problem. Seems like when I was a kid I could go out and put several hundred rounds of cheap bulk ammo through my 10/22 and have no problems what so ever. I'm wondering if there is a solution short of running a bore snake every 100 rounds. Thanks for any advise.

I'm used to extra cleanup with Remington .22 ammo. If you got 1,000 rounds through with no misfires, it's a good thing. You shouldn't have much trouble getting rid of that leading. It's not hard lead. A good lead solvent will help.
Get yourself a USGI M16 cleaning kit or just the rod*, and some brand new USGI M16 bore brushes. About two or three passes with one of these things (which are MUCH tougher than Walmart or gun shop civilian .22 brushes) will knock all that crap out most rikki-tik. And no, a GI bronze bore brush will NOT hurt your barrel. Been cleaning my .22s with them for decades.
*GI bore brushes won't fit most civilian cleaning rods--different threads. :evil:

I used a Hoppes bore snake and bore gel and it worked great. I was wondering about the copper jacketed rounds. I have read some reports that this ammo is bad on the rifling, and some that swear by it. I pretty much use only jacketed rounds on my larger semi auto rifles, but never on a rimfire.

I only use nylon brushes anymore. You can hurt the bore with a metal brush and really its not necessary. The bore will clean up very quickly with a few passes of the nylon brush wrapped with a patch and a little solvent.

Use some different brands of ammo. Remmington .22s are famous for doing this, especially with Ruger Mark Pistols.
If you're planning to scrub out that barrel with a copper brush and a rod, do it from the breech end of the barrel. This way you will not take a chance in damaging the barrel crown with the cleaning rod.
