Just picked up some Hornady sabots (50 cal, .430) and some .430 -265gr FN interlocks last weekend. Any one been using this combo?? I will start with 90gr Triple 7 or JSG FFFG, and work my way up. I figure that the 265 FN was designed for the 444 marlin @ 2300 fps, so it should be good in a muzzleloader @ 1900-2000 fps. They work pretty good in my 445 Supermag loads, so its worth a shot...
