I casted up some 310gr bullets for 44mag, and I usually run these in front of 21.5gr of H110 with great results. I'm looking for a lighter non magnum load. I had previously used Unique for a much more tolerable load for extended plinking but can't find my data. Manufacturers data is scarce if existent at all. This is not a commercially available bullet and most info found is for magnum loads. Anyone using these bullets or have any info on the 44 heavyweights?
