I have a Sheridan Blue Streak that I have had for some 25 years (I have owned 4 of them over the span of 50 years), an R-1 that I rebuild that's 34 years old, a Feinwerkbau 65 with the barrel weight and palm shelf grips and my last purchase was a Evanix in .25 in Nov of '15. At first it would shot anybetter than 2" at 50 yards and after installing a Huma Regulator and tinkering with that over a month time period I now have her shooting JSB's (25.4) into .410" @ 50 yards.
