That make a lot of sense yondering. Thanks... I will not use the small base die. Looks like the RCBS presision mic is a good thing to consider. I've been wanting to give one of those a try as well. I've used the case gauges before too. Nifty little tools. I appreciate the comments..
I use the same dies for the AR as the bolt guns. Never used a SB resize die. Size them like you would for your bolt guns and ensure function as you would for any rifle. I push a little more for the ARs but not much much BSA. You won't have any troubles making it shoot.
