Kral barrels?

I bought a Benjamin Cayden .22 (manufactured by Kral). It comes with a 23" choked barrel. It is pellet fussy (shoots lights out with JSB's and AA's, not so well with H&N's). I have no idea what the twist rate is. They tend to be well made and accurate. Mine will shoot 1 MOA to 50 yds. Contact Troy Hammer if you need more info. He's the expert on Kral rifles.
 
Stretch, thanks, you found yours liked the softer lead then, read elsewhere they did not do so well with MRD 25g, did you try these?.

As for Troy, I don't want to torture him ( or anyone ) with direct contact.

Steve, everything!

History, way they are made , are they consistent in manufacture, twist rates, choked ( covered by Stretch ) what they like to shoot, ( touched on by Stretch ).

Hopefully others can add Thier experience, we could have a Kral barrel information bomb.

Thanks.
