I am looking for any older loading charts for MEC loaders. I have a lot of MEC's: 310, 400, 500, 600, Versa MEC, Hydra-MEC, Sizemaster SM77, also have a Super Sizer SS77. Looking for charts that give loads and pressures for felt wads not plastic wads. First started loading around the late 1960's while in the Navy.
Don't know if will work
