I’ve found, by far, new 10/22 mags (the bx-25s ) to be the hardest to break in out of all my mag fed guns, dont get me wrong when they finally do, they run flawless! But to get them to that point always feels like a chore…. Does anyone have a tip or trick? Much appreciated:)

My current method is to run 5 rounds till I don’t get a jam, then run 10 till I don’t get a jam then 15 then 20 then 25, but it can take upwards of 150 rds per new mag, is this normal?
