Turns out the powder I was using for those 139gr bullets was too slow.
I was looking at some load data for Hornady 8mm Mauser 125gr bullets and noticed all the powders listed were different than the ones for 150gr+
Switched to IMR 3031, working my way up from 47gr and the groups kept getting smaller.
just need to see if I can tighten these up a bit more.
Apparently the Kar98kcan shoot lightweight bullets.
~2" group @ 100yds
