According to DIANA Mayer & Grammelspacher GmbH & Co.KG, yes, the 46 Stutzen is available in .22, but can you find one? Another thing it took me quite a while to figure out is that the barrel length is NOT the same on the 46 and the 46 Stutzen: the 46 is 17.3" and the Stutzen is 14". This is why they show lower velocities in the Stutzen. Still, a very pretty gun.
I owned the stutzen in more ways then one but my brother ran it over...lol.
The diana model 54 airking is amzing.The sliding action gives it no recoil and so accurate..Both guns are sweet warren.
I've always loved full stocked guns this one seems just right . I've found them for sale at many places in .177 but not .22 .As Duncan says above Diana does list them in .22, finding one seems to be the trick . If you happen to find two - you know where I am , 'k ?
What part of the fps figures aren't you getting? The manufacturers stated velocity or the after-import- new-upgraded-make-it-faster-because-thats-what-sells velocity ?
