I've been using a Lahman sight vise, it hasnt been working too well because every time a shoot it jumps and I have to reset it. Today i took off the front vise and through a sand bag that i use to weight down my pickup on the front of it. It worked alittle bit better but i am still having problems getting good shot placement. Im thinking about getting eaither the Shooters ridge Deluxe rifle rest or the Hughes range rest from cabelas. What does every one think?
