Sounds like the kick of the gun is affecting your shooting a lot. Get a Simm's Limb Saver (or other top quality) recoil pad. It will make shooting that kicking mule seem like shooting a dove load. If you have room in the stand use a bipod instead of a monopod rest, or build a rest into the stand. The Limb Saver pads go on all new guns I buy, don't matter if there is a pad already on the gun or not.
