Rifle is a Bergara Premier with a 28" Bartlein Heavy Varmint. Peterson brass Ramshot Grand powder Fed 210m primers.
53grs-59grs powder charges behind Lupua 6.5 Max Long Range bullets and Sierra 145gr TGK
53grs average 2870 FPS 1/2 MOA at 100yds
worked up loads to 59grs and STOPPED at 59 grs 3156 FPS is a MAX load.
I settled on 57.0 Average Velocity of 3,031 with under 1/2 MOA at 100 yds with both Lupua 144 gr Max LR and Sierra 145gr TGK.
Purpose of this rifle is long range steel shooting. It actually needs a heavier barrel, heats up too quickly.
