I owned a Beretta 24ga, fairly briefly. I was shooting skeet with it one day and, as usual, dug out a couple extra shells from my bag just in case. Someone else wanted to take a couple shots, so I had to use the extras in my pocket on station 8. No problem with the first one. The second one slipped past the ejector when I dropped it in but otherwise seemed OK. Figured I'd worry about getting it out after the shot. Also fired just fine. Wasn't until I got it out that I discovered that 2nd extra 24ga shell had actually been a 28ga.
