Not the landsharks but I have killed deer with the 190 grain treeshark... they leave a hell of a blood trail and fly great. I have some 190 grain simmons Interceptors also and they fly great.
Gotta do a little "buffing" on the edges to get them hunting sharp. Otherwise, I'm anxiously awaiting Ohio's Archery Deer Season opener, on September 25th.
I'll be shooting these out of my Obsession Fusion 7 at 56# and a 29" DL with a TAW of 480. I gotta see how these things penetrate.
