maudite,
I have 2 of the Beretta's that I currently use for skeet and sporting clays shooting and bird hunting. I can honestly say that I've never had an issue with it NOT firing the bottom barrel. I shoot 2-3 times a week and 50-75 rounds each time. I don't wipe until I've shot a complete round.
The only thing that bothers me (but I fixed it) was the flash from the cap on the left side. Now I wear a wrist cuff.
I also had an ASM over-under. It was a reproduction "kit" sold by Armi SanMarco. I sold that firearm to a fellow at a local hunting club and he used it for bunny and pheasant hunting. He loves the thing.
As far as the ramrod breaking, I use a range rod so I've never had a problem there.
I took one to Katy, Texas, for sandhill crane hunting with the BlackPowder Waterfowlers. Unfortunitly the cranes were 75-100 yds away and I we never got a shot.
I normally snap two caps then add
