TomM,
I only have game experience with my 280 using 139gr. SSTs/IMR 4831 at almost 3K fps. I killed 4-5 whitetails from 40-220 yards and they worked just fine. Had two cases where the exits were rather large but nothing horrible and nothing that I would in anyway state "failure". For lung shooting deer they're pretty dang good. I'm switching to the standard Hornady SPs in the same weight though as they're readily available locally and probably won't tear up as much meat on deer that I shoot. The places I hunt in NC and WV you could plan for a 200+ yard shot but would end up getting a 30 yarder on a quartering deer. I don't think that the SST would "fail" me as much as it would tear up more delicious red meat than I'd like. Of course SE whitetails aren't a real tough test for any bullet in my experience. I've found that a 243/100gr put it's to them in good fashion so my tackle doesn't need to be very hardcore.
