RHC,

If going the .223 route, twist will be important. On the Kimber's (1-9), it seems to be hit or miss on whether they'll stabilize the 75gr. A-Max.

Unfortunately, my Montana is a miss with the A-Max. I've got some 69gr. Scenars and 62gr. TSX I'm going to test this weekend in the Montana.

If nothing else, the 55gr. TTSX shoots very well in my rifle, and kills deer and feral hogs with aplomb! grin
