I’m resizing 223 with a small base die for mostly blaster ammo but want my brass to last as long as I can.
I know the SB is meant to chamber more reliably in case you come across a tight chamber. I don’t think that’ll be an issue for me as I have no precision barrels.
I never thought it made much difference except for taking the base down about a thousandth. Now I’ve seen where it looks like the length grows a few more thou with the SB die than the FL which means more thinning and working, etc.
I’m just wondering if it’s worth just getting a single FL die or not a big of enough difference to matter.
