Last year I decided to try out the Grim Reapers, I think they have about a 1 1/2" cut. Never really got to use them on a deer so I'll be shooting them again. I shot Muzzy's for years and love them, have tried mechanical's in the past and didn't really like them, 2-3 years ago buddy at worked talked me into using Swackers, after shooting a 10 pointer and tracked him 700+ yards decided maybe I didn't want to use them. Heard a lot of good reviews on them so hopefully be able to get a couple pass thru's this year.
