stupid problem

I would say SAFriday's suggestion is going to be your best bet. Vinegar does not play well with bluing.
As far as a "pretreatment" before shooting clean the bore really well and run a couple of patches with Tetra, Royal Purple or Mobil One and let the bore set wet for a couple days.
Dry patch it before shooting, it should help with cleanup later.

Maybe try some barnes cr 10 but dont leave in the barrel for more than 15 minutes, its pretty strong and I think melts about anything. However, if you leave it in your barrel for more than 15 minutes you run the risk of pitting your barrel. Its made to clean leaded and copper fouled barrels.

CR10 is just copper solvent wont do anything for lead .

Most metallic lead deposits associated with rimfire cartridges are actually aggregates of wax/lube with lead. Solvents like B12 Chemtool can have an effect on the wax. Have one of those jet lighters? Alternatively, can you mash the ball into the exit hole and drill chunks out?

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

Are you sure it wasn't a squib round that barely made it out of the barrel or was pushed out by the next round ?
That much leading and turning into a ball lodged in the muzzle brake is very suspicious.

no im not id like to think id feel a squib but maybe i didnt hundreds and hundreds of rounds of .22lr blend together....lol

this started as tons of lead around the inside of the brake and turned into a cannon ball by me fucking with it

i will say the last time i went shooting before this by the end of the session the .22 was shooting about 4 feet to the left then the first round(.223) i shot this session has a cloud of lead out the front and everyone could smell lead.....the rifle short stroked....then chugged through 500 or so rounds of .223.... i clean my rifle after every day of shooting but i dont think ive ever cleaned my brake before
