Jug Choking

Mortblanc,

Can you tell us the manufacturer of the barrel. Some after-market barrels I have tested for Remington 870 pump guns, of other than Remington make, performed poorly compared to standard police or miltary, cylinder bore "guard and riot" guns of Remington, Winchester or Ithaca manufacture from the WW2-era into mid-1980s manufacture.

I don't know if interior barrel dimensions have changed in the years since shotgun barrel manufacture has gotten away from the older drill, ream and hone process to cold forging and elongation of the tube, in the same manner as helicopter rotor shafts and the like.
