That's the hold Stan, I think it works better with a heavy rifle though, and maybe a bit more practice. I only used that hold until I missed four bullseyes, then went back to my normal hold. I rest the forearm of the rifle on my left hand, with my elbow down to the left at a 45 degree angle ? That's my hunting hold, but it does work with some success.
Some day I will try with my shooting jacket, glove and boots on, just to see if that helps any. It just takes so long to put all that on, and then take it off after 35 rounds ! And it's hard to cock the springer with all that padding on !
I have noticed thatANY change in pressure on the foe end will change the POI for the worse :-(
