Twin Mark V Deluxes in .378 and .460, both with Leicas. I was worried for a hot minute that the .460 might be more accurate, but I had impressive results with both during my last couple trips to the range. I've had my best success with 350 TSXs and Magnum in the .378, but the 350 SMK performs well with H1000 too (seated just off the lands, the load pictured chronied at 2,830 fps with no pressure signs). The .460 shoots everything well, and most loads extraordinarily. The group pictured at the bottom is a 500 grain TSX seated long at 2,640 FPS. All loads were tested at 100 yards.
