Welcome as well!! I will give you a base load assuming you can find what I like. I will give you the substitute bullet right now, 250g Shockwave. I like the Hornaday 265g flatpoint (.429) with the right sabot. In your rifle I would use 110-120g T7 FF (loose) any primer you want and one wet one dry patch between rounds. On a bad day you get three inch groups with the Hornaday 265g Interlock flatpoint. just my cent and a half.
