I've only killed one critter with a little Kimber 84M 7mm/08 (only one I've ever had) and that was a Texas Dall ( about the size of an East Tx WT) right at 200yds. I used the old Hornady Light Magnum 139 SST and it was "hot"! hard bolt lift, very flattened primers, but bug hole groups! ha Ram made a death run downhill, maybe 50 yds. All I found was fragments against the far inside ribs. This was around 2000 I think? Not sure, but I've read where they toughened the SST up a bit. I used the 139 Hornady IL over 55gr IMR 4831 in my first .280 (Ruger 77) I killed my longest shot deer in East Tx, 276 long steps, drt, wadded up against the far hide, high lung shot. Hogs, no problem, great bullet. I liked the 150 partition in my 7mm Rem Mag for WT, no meat damage! Good luck Shaman! smile
