Here is a photo of 15 pellets at 50 yards with the AMO3 stealth
The different barrel "claim" may be just the addition of the moderator? (a guess on my part) I know my 340 won't shoot that well @50, so Reapers' group is quite impressive, especially for a breaking-in session. Hard to believe Diana would tweak or re-manufacture a special action different than the 340 already in existence. Also hard to believe that the Bulls-Eye mount/scope combo could be THAT much better than my Lock-Down/EFR combo. Soooo, that leaves the 30%-70% Roadworthy equation.........nah, that couldn't be it Hmmm, wonder how it would do in .177 I got enough .22s
