Quickloads for the 7mm-08? Can someone help

rmarshall · Jan 29, 2014

Hey guys I have a couple 7-08's and the only powder I have on hand is Hunter and 4831SC.
I cant seem to find any data for hunter or 4831, well only on the heavy weights. I was wondering if there is some data on the 120 BT, 130 speer Bt and 140 BT with these two powders and lighter bullets-both have 22" barrel
thanks
