From a Peters 16 gauge shotgun shell box circa when they converted from roll to crimped shells (1950's ?). The situation back then was not like today when litigation is the norm.
'These shotgun shells MUST NOT BE USED in guns with chambers shorter than 2-3/4", guns with Damascus or Twist Steel barrels'
Hey guys. It isn't the Depression years when money was tight. You're not in a survival situation in the wilderness and you have to shoot whatever shell you have. Why not load or buy 2.5" shells if you have a short chamber? Why take the risk.
