I have a .25-06 that has a new barrel in the works. A buddy built his into an AI but when he fire formed his cases from factory .25-06 brass the necks came out way too short. So another local guy who went a similair route used .270 brass, necked down and his fire formed cases had necks way too thick that had to be reamed... Seems like alot of messing around to get less than desireable results. Should I stay with the .25-06 as is or fight the brass just not quite right battle? Thanks for your thoughts.
