I had been looking at a 450 Busmaster to replace my Ruger No 1 in 45-70.But after due deligence researching I decided to go with the .458 bullet compared to the .452 and more speed reloading with heavier bullets.Bought a CVA Scout Stainless that came with a 22.5 inch barrel,25 overall with the KDF brake it came with.Crisp 2.75 trigger pull.Loaded up a one load of H4895 (not the preferred powder) Some H4198 bought that is supposed to work best but didn't get it in time to reload with 300 grain Combined Technology bullets,325 Hornady Flex Tips, and 300 Hornady XTPs.The 100 yd group pictured is with the 300 CT before darkness got me before I could try the others.Very happy with no load development.Scope is a Nikon 3-9 Inline 300 BDC that should be pretty close to the 45-70 for drop.
