Ummm.....don't O/U shotguns generally cock the second chamber with the recoil of the first? Under the excitement of the moment, or if you only have one round left handy.....better be sure to put it in the correct...hmmmm...right or left......chamber. What if #1 goes "click," then you have to slam the buttplate on the ground to cock the second chamber...
.....hmmmmmmm....
....better pack more underwear....
Don't need more underwear, Muttly:
The O/U is for Trap and Skeet. Still deciding on either an Ithica, Remington or Mossburg Punp Action 12 gauge.
