Results of the Extreme Benchrest 2017 motivated me to do a 100y accuracy check using my FX Bobcat (unregulated) .25 cal with JSB Heavy Mk 2, 34gr pellets. Weapon is tuned to 826 f/s. From my bench, I shot 50y and 75y warm ups followed by a series of 100y groups. I utilized an offset aimpoint as opposed to POI to mitigate error due to blowout. My 100y groups came in around 3/4 inch, and I was curious as to how that compares.
