Recapping briefly, shoots like a shotgun with moderator on. Groups really nicely with moderator off...at 50. Called vendor for help. They are going to send me the guts for a .30 and see if that helps. Also suggested I put an O-ring between the moderator and the end of the barrel. Did that...wouldn't even hit the splatter burst 18X24 at 50 yds. OK as other suggested I put a Donny FL on it for giggles. No joy. Same issue. Took Donny FL off and put stock muzzle break back on and total joy. 2 groups pellet in pellet about 1/4" apart and there was a slight wind at times. That was at 50. Did pull a pactch through it and it came out almost clean. Did that before I took the above shots with JSB Hades. That may have helped. It the target had been a bird on the farmers feed all shots would have been head shots. Myabe the Commander just isn't going to like moderators. The overall length is less without a moderator. That's a bonus. Chronographed it briefly. It was in the mid 900s. Just wanted to see what is was doing so didn't shoot a string to evaluate the spread in FPS.. Will do that later if it doesn' start raining.
