I will say David has them 75 seated way too deep even for 223 service rifle loads. I'm finding 2.255-2.260 to be a good starting point. I do know if you are loading 77 Sierra otm black hills is seating them too 2.247 in their mk262 mod1 loads.

I wouldn't knock it til you try it. A lot of ARs shoot 77 SRAs better at 2.22" than at 2.25".
