I do shoot off hand but also often just lie the front across a Caldwell sand bag on my shooting bench. I have tried just about every brand and weight pellet pyramid air sells and the gun seems to prefer the beeman Kodiak double gold 10.6 G the best of all providing the most consistent group of around 3/4 at 20 yards. I may be jumping the gun on a barrel issue this gun is the same one that had breech seal issue which lead me to find the piston seal with a large chunk blow out of it and recently had gas ram installed. tonight I will be done and shooting it for a while maybe it will be fine the gunsmith I showed it to last night is a family friend and has preformed barrel chops and recrowns on many fine target rifles and today I fabricated a piece for the end of the barrel that would give a nice finish and a means of under leaver clip if I decide that it needs it. one question after a total tune like this breech seals ,piston seals , honeing , deburring and gas ram is this gun going to require allot of break in time.i also might add that i keep posting 3/4 as it's grouping but this is it's most often reproduced group there have been times for a five shoot group to nearly be hole for hole right on the mark at 20 yards but doesn't repeat itself whether on the sand bag or in my hand the same results. i know this gun will do better i can do better with my savage 17 at 200 yards.
