Another one bites the dust (IC BDS)

[3" 870 Shell Shucker]

shell shucker,  Your constriction should read 0.065,  not .65 witch is more than 5/8 of an inch.  Marty

Federal Black Cloud steel with the Flight Control wad is notorious for destroying shotgun barrels, generally tearing the the choke out of the gun or pealing the barrel open at the choke, so the wad is known for being very hard on choke systems and we are talking about chokes in the .010-.030 being permanently removed form the gun! so just think how hard it is on a choke with .050+ constriction trying to force 2oz of hard lead shot and a rock hard wad that has two hard forward facing edges getting forced through wad catchers and porting, that combo is bad mojo!
Just a little input from an avid Waterfowler that has seen stacks of barrels ruined by Black Cloud, the biggest issue seems to be loose chokes and the forward facing brakes on the wad.
