Thanks for the response. I built an ultralight rifle with a MacBrothers Element II, 22" Bartlein Barrel, Manners UC Carbon +,TriggerTech diamond, Leupole VX-5 fire dot. Hoping it will be great for an upcoming antelope hunt this fall. without scope it weighs 6.4 lbs. I can get 5 shots inside 1/2 inch running 60.5 grains of H-1000 at 2875 fps.(ADG brass, Fed 210M, 156 Bergers) Would like to try a 140 accubond and maybe H4831sc. Very little load information out there.
