Ok the forums were not working with my kindle for some reason..... so I was on my own

Yes I was shooting 22lr for the record I'm cheap when it comes to ammo and saved 1/2c a round going with cci blazer lead bullet instead of Winchester 555 copper plated I never had this problem with any copper plated stuff and I'm up over 50k with this upper.

How I fixed it.....took a very tiny punch and chipped the cannon ball into tiny pieces and shook em out the barrel it took a long time ....I'm gonna just dip the muzzle brake in mobile 1 before I shoot next time I have like 1500 rounds left....

I only put 1000 rounds of this stuff down the pipe before it leaded up like that....had over 2 bullets worth of lead in the brake
