T7, not bad with 120gr T7, is that the highest recommended load for T7, could you go to 150gr.?
122 grains of T7 is the normal highest amount of loose T7 that can be shot in most guns following manufactures specifications. My Knight will allow 150 grain, but 120 is way more than enough... the only reason I shoot 120 is for elk hunting with a .458/300 grain bullet. All of my other loads are either 100 grains or 110 - with 110 becoming my most accurate in all of my inlines...
Sometimes them darn Coyotes like to run off 200+yds then stop and look back, I'd like to suprise them!
Get a box of Hornady 10mm/200 grain XTP's, matching blue sabot, and 110 grains of T7 and you will flat out surprise the heck out of a 'yote' - problem is that it will make an awful big hole....
