RE: 30 06 cartridges
I'd check into Hornady. I was at the range last week shooting Interbonds, SST's, and Soft Point Boat Tails, all165 grain. Got good, and consistent, groups from all of them. Added bonus: the price is pretty good on them.
I've found better accuracy with Hornady in my particular rifle, but I don't have any tales of on-game performance. From what I've read, however, there are few, if any, complaints from those who've drawn blood with 'em.
Good Luck!
