SST's are great! I have loaded the 150 grainers in both 308 and 30-'06. Both loads were very accurate. Haven't got to use them for hunting yet, but if they work like the Nosler Ballistic tips, they will do you good. I believe they are supposed to retain weight better thatn the Ballistic tips. Either way, the Ballistic tips drop deer deader than hell. If you order, order the Light Magnum SST's if they make them in your caliber.
