22-250,kreiger, rem 700 pillar bedding, 8 oz trigger, lapua brass, 60 berger, vv540(36grains) .025 " jump and it makes a very small hole...in the ones! three days ago the group was 1/2 in. to left of zero, clicked right 1/2 (leupold 6.5-20) and waited to go ghog hunting. yesterday helped a buddy zero his gun and just for conformation shot the above load and ZAP! 1/2 in. to the right of zero! what is going on? all loading done at the same time, runout the same, brass all same weight, but temperature cooler than previously, AND the loaded cases were in my vehicle riding around for two days with the powder settling as if it was loaded with a drop tube,,,packed. is this possibly the cause of my shifting point of impact? the gun was shot a few prior to each test. this is a beautifully accurate load but i cannot understand the shifting poi. anybody? thanks.
if i can see you, i can touch you.BANG!(1/2 inch to the right or left).
