243 ai

[Joe O]

I shipoot a 28" + Vais break Hart 1:9 HV,(143/4lbs all up) and shoot 70gr Sierra BK and Nosler Varmint Balistic tips.The only powder I used was H414 or WW 760.I fire formed using the max load data for Hodgdon 243,and worked up loads from there.I have a .272 neck,so had to turn the 243 virgin brass before fireforming.

i think i may have found the load for my gun that likes both the 70 grn ballistic tips and the 760 powder i am running 47.8 grains i dont know how fast yet as my chrony wouldnt tell me that whole string, but i am guessing around 3650-3700fps ill find out soon. i went from shooting an inch sized group of five to all five touching in a small horizontal line when i lowered charge weight. i think i am gonna stay with this and start killing thing once i get my zero and some distances figured out
