Having a problem with my Mec 650. On station 3, the wad is catching on the "lip" of the hull, so the wad does not seat correctly, distorting the top of hull and yes making heck of a mess. Does not do this every time, probably 2-3 times in 25 hulls. Very frustrating! I am reloading once fired sts hulls with clay buster wads. Can't figure out if it is the hull or reloader causing problem. The wad guide has a small amount of "play", probably 1/8 to 1/4" of movement. Is this normal or should it be tight with no movement? Any thoughts or suggestions will be greatly appreciated. Have only been reloading a few months, bought reloader new and have loaded around a 1000 hulls.
