I currently shoot the 175gr Hornady SP interlock from all my 7x57s. All three rifles are Rugers and all three shoot about 1 inch groups at 200 yards (My FN/Flaig's Mauser is at the gunsmith for now). My load is 45gr of H4350. Don't know the exact speed but it should be around 2400 fps if my manuals are any indication. I haven't killed an elk with them yet but I have killed many whitetails. Those big bullets always exit and leave a gaping hole. I've never recovered one of those bullets and never lost a deer shot with them. If you punch through both shoulders the deer drops like a sack-o-taters and it makes a bloody mess inside them. In my ignorance, I would not hesitate to shoot an elk or any other non-dangerous game animal with it at up to 300 yards, and that only because I'm not very practiced beyond that range. I got a 416 Rigby on the way for the really big bucks.
