@thatguyshm, thanks for sharing. let me know how the 44.5gr goes if you get to test it out. Feel free to send me msg updates :)
I have 20 in Savage 10FCP-SR(1-10 twist) 308 I recently got a pretty good group, ~ .8 in (4 shot group, note im still a new shooter) with 43 grain of 4064 also [175 smk ~2619 fps w' 10.3 S-D ]. Looking to do further testing sometime soon to see if I could duplicate results.
