I just bought a hornady ap press and .243 full length dies. My friend told me to start with IMR 4350. I also have cci 200 primers and once shot hornady brass. I used box loads for break in because I wasn't set up yet. I have 95 gr Berger vlds, hornady 87 gr hpbt, and 95gr smks. Any starting g help would be great thank you.
