I have found two good products this year. First is the Burris Fullfield II riflescope. The Ballistic-plex reticle on this scope helped me take a pronghorn at 275 yds and a 4x4 mulie at 438 yds - both with my .270 Remington 700.
The second is the Sagen, Inc. saw. This is a T-handled saw with about a 3" blade and a PVC tip which eliminates puncturing of the intestines while cutting the pelvic bone. My guide used this item and I was impressed with its ease in cutting through the pelvic bone, that I went out and got one for myself.
