Hi, I have tested two loads last weekend and today.
1. .308win 147Gr FMJBT,Win p/n WB762147N) 43Gr Varget - 2812FPS - they shoot tight groups @100
2. .308win 180Gr Super-X SP,Win p/n WB308SP180) 39Gr Varget - 2622FPS - the same tight groups too @100.
And load #2 always is 3.5' below load #1. I can reproduce this consistently.
My question is how it's possible to have 3-4' difference between groups shot using two types of bullets @100
