Can't Get a Good Load
My .308 and .223 loads all use Varget. Both rifles are easily capable of les than 1/2 MOA at 100 yds, and sub-MOA at 600 yds. Since Varget is nearly unobtainable now, I started looking for a viable alternative. I tried several powders, including Ramshot Tac. Of all the powders I tried, TAC gave me by far the worst results. I saw huge SD's and ES's in my ladder tests. Actually had 3-shot ES's over 100fps with my MPA .308 chassis rifle!!! The .223 loads weren't quite as bad, but they were still the worst I saw with any powder. I'm very precise in my reloading and use high end equipment, dies, and measuring devices, so these loads weren't just slapped together. Fortunately, I only bought 5 lbs. Maybe I'll use the TAC for .556 NATO loads, where "minute of man" accuracy is acceptable. For what it's worth, I was able to equal my Varget load accuracy for the .308 using IMR 4166, but of course that can't be found anymore either.
