dse Report post Posted November 20, 2017 Don't really know as far as temp stable but Retumbo was the most accurate powder when I was loading for my 300 Rum with the 200 gr eld-x. Share this post Link to post Share on other sites

lancetkenyon Report post Posted November 20, 2017 Retumbo is more stable than IMR7828SSC. H1000 is a good one to try with the 180-215 bullet weight range. Share this post Link to post Share on other sites
Presmyk Report post Posted November 20, 2017 H1000 better then retumbo on 200 grn bullets? Share this post Link to post Share on other sites
dse Report post Posted November 20, 2017 The 3 powders I tried in mine were Retumbo,H-1000,and Rl-25. Retumbo was the most accurate and Rl-25 was the fastest with the 200 gr eld-x. All we're sub 3/4 moa with Retumbo being just under 1/2 moa. Rl-25 real close to 3300 fps. Share this post Link to post Share on other sites
