Depending on the quality of the barrel from 9 to 20 normally some barrels take more
and factory barrels have taken as many as 60 before they settled down. On these barrels
after 15 rounds I shoot 3 and clean and at some point I will just start using it if it is good
enough to hunt with at close range.
Some of my best barrels have stopped fouling after 5 or 6 rounds.
Thanks J C Custom Iam shooting a tikka tac and cleaned the barrel every 3 rounds for the first 30 rounds,its -20 here and I seem to getting machine oil on my patches.The groups are getting better,Iam going to heat the barrel up with a longer volley and see if it cleans up.Nice gun its worth the extra effort.
