After waiting several months for AOA to get in an HW97 in Blue Laminate in 22cal, it finally arrived. I have only sighted it in at 18 yards last night as I just finished up the tune. Below is a pic and some FYI info if anyone is interested. The tune is a standard Maccari tune kit with Vortek piston seal. This is the first HW97 I have ever owned in .22cal, so I have nothing to compare the numbers to another one in .22cal. The gun was a great shooter out of the box, but too twangy for my taste.
Below are some before and after chronograph results.
Before:
H&N FTT 14.66 5.53's 677fps
Predator GTO 11.75's. 805fps
Barracuda Green 12.96 763fps
H&N FT Green 10.03 886fps
Crosman 14.3 687fps
JSB 14.3 619fps
After:
H&N FTT 14.5 5.53 726fps
Predator GTO 11.75 861fps (19.34 foot pounds)
Barracuda Green 12.96. 812fps (18.98 foot pounds)
H&N FT Green 10.03. 953fps (20.23 foot pounds)
Crosman 14.3 756fps (18.15 foot pounds)
JSB 14.3 696fps
JSB 13.43 738fps
JSB Hades 15.89. 691fps

Couldn't say for sure. It doesn't sound like a 5 grain .177cal pellet shooting out of an R1, so it has that going for it. That was a chronograph test above of what I thought it might like.
