So, I'm wanting to build a load for my AR15, and was looking for a powder that I could maybe load for my AR10 with. Calibers are .223 wylde and .308. I have a load for my bolt .308 that uses IMR 4895, and I dont believe that's a good choice for .223/5.56. I bought a pile of 69gr SMK, and some CCI 400, and was considering Ramshot TAC. However, I went to a LGS the other day, and he had a bunch of Hodgdon Varget. My Sierra manual has decent looking loadings for both .308 and .223, and actually had their "accuracy" load come out to be the one with Varget. My question is, did I go wrong buying it 4lb for $100, and am i to expect a let down, or confidence when using it for 69gr smk out of a 16" 1:8?
