[QUOTE="Berrnard, post: 3073814, member: 128207"] still looking for 257 head stamped brass but decided to play with some of my 7rm brass. it is 1x fired and deprimed, not sized at all i stepped down to 270wby then to 257. the untrimmed length i am getting is 2.530 or less, my longest so far is 2.533. one piece is 2.500. i thought annealing may help stretch the brass during sizing but i see no or minimal difference. i also tried unannealed brass first. hornady book states max trim length is 2.539. is this safe or am i getting on the edge or past it on too short? what say the gods of LRH reloading?
