Thread: Roll crimping 308 subs

I found a wild increase in accuraccy just by crimping mine

I dont know what a roll crimp is tho, I just used the one in the lee die set box and followed the instructions included

at 30m my group went from 12" or more down to about an inch

this was 300blk and robs 151s, I mostly used 165gr nosler BTs in the 308

I also noticed it makes for less occasional one that pops above the sound barrier,
