[QUOTE="Trickymissfit, post: 690240, member: 25383"] good post Bart! I have the same issue with the butt pad, but I'm steadilly working that problem out. You also can get it from the front rest as well, but the amount it gives will vary. High velocity increases bullet spin and thus increases the error in the C/G (.0001" in the C/G is known to give .093" spread at 100 yards). But on the otherhand that spread will also go sideways as well as vertically. Another way to cause the groups to spread vertically is with a muzzel brake. Most folks don't reallize this, but it will. gary [/QUOTE]
