I tried some 420 grain hardcast .459 gascheck bullets in my .458 Winmag Interarms Mauser Mk 10, using 20 grains of Unique (Max allowed 22 grains). The gun sprayed all over the paper, with the bullets tumbling badly. The load shows maybe 1400 fps... maybe too slow to stabilize? The gun shoots factory 500 grain soft points into 2" at 50 yards with iron sights. I'd really like to shoot cast bullets in this gun, as jacketed bullets and especially factory loads are really expensive. I drive the same bullets out of a Winchester 1886 in 45-70 doing around 1800 fps and it's a real tackdriver. If anyone has any suggestions I'd really appreciate it.
