RE: 30-06
Anything that will shoot well, will kill a deer via 30-06....
180 grain Federal Blue Box flat slams 'em per factory loads, and just about any good cup and core as well, per reloading, regardless of grain weight. Deer simply are not bullet proof.
If you like the notion of loading TSX's the 168's are, IMHO, a bit much for whitetails..but if you like trainwrecking them they are bullet.
Just recieved a box of 150 TSX's to try, though I'll be doing less deer killing with my '06 with the completion of my .243AI......
