so i’m using the lee dies to Fl size my 7.62x54R brass. i know the lee expander plug is .308. would i get better case life if i swapped out the original expander mandrel to .311. .311 would still give me .003 of neck tension. i’m sizing my noe 314-210-run bullets to .314. i’ve measured a fired case and the ID is .316 OD is .336
