I have been using H322 in the past for my handloads and needto restock but have noticed that Reloader 7 looks like a good option to pick up some speed. First I have an OLDER barrel that is a 1:9 twist and a SAAMI chamber. I have been running 31 grs of H322 and 90 grn TNTs with good results. Should I make the switch or stay with what i have. I like my groups @ around .75 MOA. Will I be giving up accuracy to gain speed by switching to Reloader 7?
