A few things for reloading, MEC males shell raiser plates for shorter length shell in 12 & 20 gauges, but not 16 for the 600 Jr. press. It only matters on the last 2 stations, and you can make a shim 1/8" thick yourself. My concerns are never with plastic or all brass hulls, only with paper hulls! The case walls are over twice as thick, and that only matters in the forcing cone area!

I shoot a 1904 model 97 all the time with Skeet and Sporting Clays loads, and sometimes even with Federal Papers! My field gun's tolerances just aren't that tight!
