All my loads are the same as I am a little anal about reloads.(68.5grs.H1000, Hornady cases, fed215m primers, I tried cci magnums but still got same results all bullets are seated to same depth, coal is 3.519 which is touching lands. I tried backing off and jumping but that didn't work.)
Anyway I found the same thing fouled barrel first shot is poa. One note I don't beleive in cleaning out copper, carbon yes, copper only after several hundred shots or when accuracy drops off. But that is just MHO.
Here's my load build (most of it anyway)
Hornady brass headspaced off the shoulder by .0015" to .002".
Retumbo - enough to get an average MV of 3020 fps.
Berger 168VLD H (orange box) seated to .010" off the lands
My observation of Berger VLDs is they are particular about how they are seated in relation to the rifling. A shooting buddy also has a 7mmRM that won't shoot a decent group unless seated almost .080" or more back from the lands. My rifle likes them to touch but I won't do that with my hunting guns hence the .010 leade. Sticking a bullet in the bore is bad JuJu that could end a hunt or worse. This may be meaningless but his barrel is an original Remington factory model from the 70's whereas mine is a relatively new custom barrel.
Another observation is that VLD bullets are a long range design. Shooting groups at 100 or 200 yds hardly ever yields a one hole group. My 300+yd groups always show better performance and better as the distance gets longer - to a point within reason. I know I'm not the first to see these phenomena as many have mentioned it here and elsewhere before. I am able to corroborate what they have said.
