The 3 pills I'm playing with now are 150gr ABLR, 162gr ELD-M, and Barnes Burner 171gr in a Rem 700 long range.
Nothing too ground breaking, but none of these shot well seated long. IMR4831 for the 2 lighter weights (was down to single digit ES with the 162's) and H4831 for the 171's. The 150's and 171's seem to be the best so far, the ELDM doesn't give me consistent groups...one tight, one crap, one meh, even though velocity was identical shot to shot basically.
I did try something fun last time out....all those left over shoot-n-see repair dots I never use, they are about 3/4" across so I stuck a bunch up randomly at 100/200.
Figured if I could hit each one, single shot on each from a cold bore, the gun,ammo, and scope was working.
