Preferably if you've got a few seasons and at least a few thousand rounds on your semi and which mods did you have to make to get reliability out of them?
I've got a 3.5" Browning A5 that I've run for 2 seasons: somewhere around 1200 rounds on match time and another 3000 outside of matches. It didn't run target loads 100% at first. Chopped a few coils off the recoil spring and that seemed to help. Target loads are all good, low recoil slugs fail to cycle all the way sometimes. Runs a ghost load fine.
