I'll start off by saying; Ive never killed an elk with my bow, as a matter of fact, Ive never killed anything bigger than a 150# Whitetail with my bow. So, with that said...

I shot MagnusII2 Blades (125gr.) this year out of both my compound and recurve, and I dont think Ill ever shoot anything else. Both deer I killed (Yes, I realize a whitetail is a far cry from a 800 pound bull elk) were dead in less than 80 yards, my last one in less than 50. The Magnus completely blew through my last deer, with a quartering away shot, shooting "only" a 46# recurve. He didnt bleed well because of the high exit wound, but the doe before him (Double lung shot / 52# Compound) left a blood trail a blind man could have followed. Anyway, both broadheads are in perfect condition (Still Shave Hair!) after the shots.

Oh, I had to start shooting a single broadhead at a time with both bows, because I was tearing off too many feathers and spliting too many nocks...on my field point arrows. So yes, they hit right with (orjust plain "hit") your field tips.

The Stingers would prolly fly better from a high speed set-up, and if you're wanting a three blade, check out the Snuffers.

Hope I could help...just my two cents...
