sbhooper,
I believe the 150 .30 SST's have been beefed up considerably. Went on a deer/pig hunt in South Texas last fall, and all the rifles used among a number of hunters were 22" barreled .308's, and all the ammo used Fiocchi factories with 150 SST's. Muzzle velocity was around 2800. We killed more than two dozen animals, and the SST's not only didn't grenade, we never recovered one, even on angling shots through fairly sizeable pigs and bucks.
