How do you stablize to make an accurate shot on antelope (and hence, possibly a long shot)? Do you use some sort of a rest such as a back pack or rolled up jacket? Do you use a collapsing bipod? Do you just sit and hold your gun? What effect does the wind have on your shooting position stability? I'm going to Wyoming and have heard the wind blows 20 - 30 MPH most of the time. Are there any tricks or techniques that can improve shooting stability?
