I love 'em. I've shot three deer, half a dozen or so antelope, and a number of hogs with my 6.5x55 shooting 129 grain SSTs. On shots from close to nearly 300 yards, I've never recovered a bullet. On-game performance has been excellent, with evidence of complete expansion and massive tissue damage. Interestingly enough though, I have noted that they don't cause as much meat damage/waste as the Barnes I shot before or the 125 grain NBTs I shoot in my .30-30 AI. They're not a real "hard" bullet, and I suspect that in a higher velocity cartridge you'd get more explosive results. I think they're about perfect for mid-range cartridges like the 6.5, .270, -06, etc. For that reason, in your 7, I'd recommend the 154 grain version.
