of you 22cal 54/56 Diana owners, what pellets, chrony results and accuracy are you getting?
My 56 was custom tuned by Scott Schneider at Motorhead. It shoots the AA 18.0 grain pellets best of several tried. It shoot at +/- 720 fps. Will shoot < 3/4” 50 yard groups.
Minute of soda can at 200 yards with OLD brown box 14.3gr Crosman Premiers and OLD 14.3gr Crosman Copperhead pointed. The current 14.3gr pointed Crosman in the 175 count tins are the current versions.
One of my newer 54s shoots 18.1gr AA almost as good at 200 yards.
I had old chrony notes but they were never recovered after I lost that house.
