My '96 is shooting a 140gr Hornady SST over 41gr. of H380 at 2500fps fired by a Win Mag primer with a COL of 3.105.
I screwed up last year, shooting a buck (15 yards) without grunting to pause him. He stepped just as I pulled the trigger. The SST hit about 12"-18" behind the front shoulder, resulting in a classic gut shot. The SST liquefied the internal organs. Messy field dressing, but the Old Swede did her part. As usual, the problem was the nut behind the buttplate.
