Yeoman,
I didn't mention Hornady XTP's. I know a few guys here that like them. I shot my longest BP shot to date on a deer w/one. 245gr 45 cal w/ the blk sabots, 80 gr of FFG Goex @ 130 yrds on a boardside deer w/a clean pass through.Acolor blindcaveman could have followed that trail..
XTP are very cheap and though they are pistols bullets they perform excellent @ longer ranges as they have slowed up and mushroom great. I haven't tried the gold dots but I sell more GD rounds to LE depts and that new HST federal tactical bullet will repalce the Hyro Shok which looks just like a hornady xtp. Both great stoping rounds.
I do believe if your a long range shooter the SST is great but I have never shot that far again on a deer so some one else would have to advise you on bullet expansion.
I have heard great things about the harvester Sabertooths as well as the all copper red hots which are barnes bullets. My freinds w/ the Savage ML's love those Barnes expanders in 300 gr and they are big hole makers.
Leyt us know your progress.
LOL, SHills
