I share some groups comparing my Evanix Windi City .25 with the FX smooth twist barrel (top three crosses); my Woverine HP HR. 25 (middle three crosses); and my Vulcan 2. 25 (lower three crosses)
Evanix was shooting JSB’s 25.4 grain at 47 foot pounds.
Wolverine was shooting JSB’s 34 grain at 54 foot pounds.
Vulcan 2 was shooting JSB’s Hades grain at 46 foot pounds.
Target was at 75 yards.
The shots at the first left crosses implied a learning compensation process, so center and right crosses shows the better the performance of each rifle
