Got a brand new upgrade, been in the vault since 97. Never fired! It has the medium weight NM barrel trigger and flash suppressor with 3 20rd usgi mags. To break it in, should I use fmj, or fmj moly coated Black Hills ammo? If so, can someone here describe the process for breaking in? Also, been reading horror stories on cast receivers and parts breaking. How can I know if the receiver is cast besides calling SA? Thanks for your help, by the way, have ample supplies of both above mentioned ammo.
