This has been posted on Saubier as well, I know a bunch of you small caliber nuts are over there as well. For you veterans of forming 17FB from 221FB, what is your preference? 2 basic differences between 17FB and 221FB are the shoulder angle (30 vs. 23) and the shoulder diameter (17FB is ~.005" larger). Use the 221FB bushing die and leave the shoulder a sloppy fit, or finish with the 17FB die and let the shoulder mushroom? Is there a consensus on the best method?
