Anyone out there use this powder? ,been experimenting with my 243 AI shooting 40 gr of this powder and 75 gr Vmax with consistant deadly accuracy,,,no chronograph so see speeds but looks like my next yodie gun!
I use it in my 308's and 243's. IMR 4895 is reducing slightly better groups, with minimal testing time so far, in higher temperatures. I haven't had enough time to get to the range to do some proper testing in a while.
I am continuing to use the 4166 because all of my loads j have developed so far are under 1MOA. Still not the groups I want but it's a good start.
When it first came out a couple of years ago, I tested it side-by-side with Varget in a 308 and could find no difference in group size. Never chrony’d it so can’t speak to that comparison. I currently run it in some 6 Dashers and with my deer load it pushes a 95 gr bullet to 3030 FPS.
Found the powder meters reasonably well. The standard deviation was extremely low in my 22-250. Can't wait to try it in my 204 Ruger I doubt it will be more accurate then benchmark. Should be fun trying
