I'm a long time reloader - 50 plus years - but I've always gone by developed loads with no variance. Now I have several pounds of Hybrid100V, boxes of 150, 170, 175, and even some 139 grain psp/pspbt/semi-spitzer bullets and a pristine 1941 custom 8x57 Mauser that I built... and no data to use loading.
Thoughts? I see the burn rate is between H4350 & H4831 butno data for those either? Is the case too small forthe caliber or... I use this powder in 7x57's with good success.
