I guess for a light rifle, I would vote for the 7x57. I have used it wild boar hunting with excellent results, not to mention deer. For my elk rifle, I just finished a 338-06AI, with muzzle brake. Shoots like a champ. I do not like belted magnums, just my preference, and I wanted to build some sort of wildcat rifle just to be different from my norm. I haven't really had the time to take it out and build a load yet, but the limited rounds I have put through it were pleasantly surprising. I bedded it into a Hogue rubber overmolded stock, strictly utilitarian, but adequate for my hunting purposes.
