I have the above gun with �ammunition 22� stamped on the barrel.
The proof marks are�22 L� which I presume means its chambered for the 22 long.
A 22LR round will chamber but there is a little resistance .
I gather the only difference between the two rounds are projectile weight,would it not be possible/advisable to run a 22LR reamer into the chamber to use regular 22LR ammo?
Would the rate of twist be different between the two?
As an aside it has engraved on the receiver �made expressly for A Hajee Dossul and sons Karachi�
Anyone shed any light on who these guys were?


Cheers,
