Seems the Longbow and Omega getting the thumbs up. Have a Stringray Express in .20 cal with full Webley Venom tune and it's a lovely bit of kit. Don't forget the Cobra Webley Venom did based on the Tommy. Only 12 made and they shoot AMAZING. Mach 1.5
That and a long transfer port that forces the air to do two right-angle turns before it gets to the pellet.
In a pistol, those aren't such big issues, and they allow an appealing compactness compared to the more conventional layout. In a rifle, the performance limitations if the design are more apparent.
And I've never been sure about the quick-change barrel, from an accuracy point of view.
Don't get me wrong, they are fascinating, charming, important rifles. But as a shooting proposition, the LJ BSA and similar knock them for six on both power and accuracy. Which is probably a factor in why Webley replaced the MkII with the BSA (via Diana 45) derived MkIII.
