With Lapua brass, GRT says your close to max at 33.5, with Alpha brass about 32.7 these numbers are rough.. so start low work up to it.. but this should get you near the ballparkIm just looking for other options with powder that i already have . I have about 4lbs of varget left and have 10lbs of H-4350. So i would like some load data and exspected fps with 4350 and a 105 . My barrel is 28" long . I just started looking for more varget with no luck so far
