What is your goto load for the .204 Ruger???
I basically have 2 loads, both with WW brass and Rem 7-1/2 primers.
1) 28.0 grains of H335 and 32 grain Hornady or Nosler bullets. (Sierra would probably be fine, I just haven't tried it yet.)
2) 27.5 grains of Varget and 39/40 grain Sierra, Nosler, or Hornady bullets (Haven't tried the Speer TNT yet).
I've already worn out one barrel with those two loads and I'm onto my second. Imagine my surprise when, after a load workup with the new barrel, I came back with EXACTLY the same loads.
