Barnes 450gr TSX TAC powder. COL 3.565 crimped in second groove from bottom. 75gr 2083fps 77gr 2140fps 78gr 2166fps 80gr 2204fps
I stopped at 80gr. This is 1.5gr under the Barnes book max for 458 Lott. I see no signs of pressure, and extraction is easy. Primer pockets still tight after 3 loadings on one of the cases I was keeping track of. I was only able to get 2140fps with this bullet in my 21″ Winchester 70. This R8 has a usable barrel length of 22.5″. So I think I should be able to do better, but not really that concerned. I’m betting the CEB Raptors and Solids will give better velocities as they have in the past with my 21″ gun. I was easily getting 2250fps with that gun and the 420 Raptors. Now with being able to use the Talon tips in this R8, I should be able to come up with a heck of a load."
