I'm thinking a 250 TTSX, though I've never loaded it, as I retired my H&H. My favorite in the H&H was, a Hornady 270 SP, pushed by 82.0 grains of WW 760,CCI primers, RP brass. The above load is over listed max, but shot extremely well in my Model 70. My best 4 shot (I blew the group with 5th shot) was just under 1/2 inch. memtb
