If you're shooting from an AR15 platform I would strongly suggest the RCBS SB TC die set #28007.
I and others have had issues with a raised ridge at the base of the cartridge using other die sets.
A side benefit is you can shoot that sized brass in any 6 ARC rifle.
I try to keep my shoulder bump at .003-.005 on my AR15's. Adjust your die to your liking. I don't use the Taper Crimp, only neck tension. And remember, if you want consistent performance you need to anneal them cases!
P.S.
I may be a newbie here but I've been building and shooting AR15's since the early 70's!
Been reloading since 1966.
