reloading shotgun shells is easy, follow the directions closely and check powder wieight the bushings are throwing with scale.. dont load the first shell thru if possible so to let powder and shot settle, dump it back into the tubes if you can... use good modern powders as they are cleaner burning and somewhat less temperature sensitigve.. dont go cheap on components, garbage in, garbgage out.. i count number of reloads on hulls, but it will be come obvoise if theve been shot too much.. dont excange compononents.. the bigest diffence from rifle reloading is that you can put doulbe powder in a shotshell and still load it.. this can be dangerouse so be carefull.. you will see it on the wad pressure will go up if you wathc there.. alot is going on pretty quick with a shot press so go slow at first.. larger shot can hang up in the drop tube, or not go thru the bushing correctly, when something is wrong like leaving out the shot, the shell wont look right or the criimp will punch in.. i would get or order a manual for the press from the manufacturaer.. if youj cant get setup advice or a book on your machine, the press could be a problem for you.. the press could already be setup for crimp and etc.. you may just need bushings and wad pressure adjustment.. dave..
