Cutting the chambers to 3" and with long forcing cones in front of the 3" cut would bother me A LOT. I also have a Sauer VL&D Knockabout, and mine has finely struck barrels already. Cutting a 3" chamber and then a long forcing cone is removing a bunch of metal right where pressures are highest. I don't know anything about Aleems Gun Kraft, but they may have messed up a nice gun with that 3" chamber. I would have a gunsmith who specializes in double guns to check it out and measure the wall thickness at the front of the forcing cones before I would shoot it again. Modern ammo is pretty stiff. Just my 2 cents worth. I am kinder to my old pre war German guns than you have been.
