Freakycamo Report post Posted January 30, 2018 I am shooting a Ruger American predator, 143- ELD-X and using 43gr of IMR 4451 and it shots lights out. I think it’s shooting @ 2733 fps. 22" barrel. Share this post Link to post Share on other sites
Coach Report post Posted January 30, 2018 Not to derail this, but this is the first I've seen about IMR 4451. I've been using IMR 4350 in just about everything I reload for - it just seems to work out best for them. Is IMR 4451 a replacement for IMR 4350 as well as H 4350? 1 Share this post Link to post Share on other sites
PRDATR Report post Posted January 30, 2018 Anyone using RL16 or any of the other RL powders? Share this post Link to post Share on other sites
STOMP442 Report post Posted January 30, 2018 Yeah R16 works really well too. I have done two creeds now that both liked 42.5gr with velocities in the 2850 range. Half MOA or better with single digit ES. Share this post Link to post Share on other sites

IMR 4451 splits IMR 4350 and H4350 in burn rate. So yes, it is almost a direct replacement for IMR 4350. https://www.hodgdon.com/wp-content/uploads/2017/09/burn-rate-color.pdf Share this post Link to post Share on other sites
