Hi all. I'm not new to reloading but new to reloading belted mags. How and were and with what do I measure on my fired brass for sizing and how to properly setup my die. Any help and advice would be greatly appreciated. Almost wishing I would have just spent the extra money on one of Riches cartridges and would t have the headache of the belt. If it matters I'm currently using the hornady standard sizing die and ADG brass.
