What powder to Use

909 Views 2 Replies 3 Participants Last post by  angsniper
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?

Thank you guys,

For the 90 GR bullets you should have better luck with RE7 and H4198 over H322. Nothing is a guarantee of course.
