I think I'll start with the TAC data since that is what I have on hand, I'm considering other .223 powder and haven't decided between. H335, Benchmark or Varget.
TAC has been the only powder I've tried since I recently got back into reloading...but so far TAC has been very good for my gun, especially 55 grain Hornady FMJBT.
It runs 75 gr. Hornady BTHP's pretty well too, but I don't think that bullet would be best for predator hunting application.
I read all kinds of good stuff about Varget, but, I also read its tough to meter.
I'm surprised this 65 gr. bullet or the 55 grain Game King isn't a bit more popular?
