Go with a Mec 600 jr. I have a 12 and a 16 gauge version and both have seen 1000's of rounds.
The AA are still good but have a disc in the bottom that some people claim will dislodge after several reloadings and get caught in the barrel. The next shot will ruin the barrel. I still use AA for some loads but always look down the tubes of my guns before reloading.
Not so, grasshopper.
Winchester AA's are compression formed and are one piece hulls. The old high base, low brass, Winchester paper target loads had a paper base wad that some claimed could dislodge and wind up in your barrel although there was never any reported instances of it actually happening. Winchester discontinued the paper target shells and started making the AA's.
