LAPUA brass, Federal 210 match Gold Medal primers,
80.0 grains H1000
avg 2853 fps ES 35.67 / SD 13.11
3/8" group @ 100 yds.
Hope this might help your situation in some way !
I'll throw mine in was at the range today. Rem 700 28" Krieger #10, 28 degrees out 75% humidity.
Mixed brass mixed amount of firings, but all fired at least once in my chamber.
208GR Amax not sorted in any way picked at random out to the box.
79GR H1000 Loaded .010 off the lands
CCI BR2 Primers.
I bet if I went all bench rest on case prep, weight sorted brass etc I could get better, but this is darn good.
.640 groups for three shots.
No pressure signs might bump up to 80GR and see if I cant get some compressed loads.
