Was down at the shop today my custom 2240 platform .22cal disco pistol is looking sweet but far from done . Still waiting on grips and shroud but the tube and barrel have been cut to 17 inches and mounted and the valve has been hot rodded . Trigger is polished and will be replaced but the truth is the #'s Starting at 2000psi first 5 shots are with 15.9 grain JSB's #1=966 #2=977 #3= 987 #4= 998 #5=1005 The next 10 where shot with 16 grain predators #6=906 #7=958 #8=965 #9=984 #10=993 #11=1012 #12=1025 #13=1042 #14=1054 #15=1084 shot down to 1200 psi It will take about a week to get it all finished setup as a 17 inch carbine with a cothran trigger and wire stock this is going to be a breakdown shooter i'am pretty happy but waiting is painful sorry i don't know how to stack the #'s

Thanks rich for your help i had a disco rifle and the sweet spot started at 1750 down to 900 psi it gave me 30 good shots. Yes i was blown away i was looking at 750 fps and would have been happy now i'am thinking of powering down for more shots .I would like 25 shots at 830 or so fps this will also be easy to pump with my hill so i'am already thnking of some hides i have down by the river where the crows gather at low tide . It's far from pretty right now but it's a tool for me knot a show piece .
