javelinablanco, looks like a good fit for someone that is just getting started in shotshell loading. I would recommend that you pick which weight you would like to try out. The 7/8 ouncer is a bit shorter and can go a bit faster, with reduced recoil. The 1 ounce is a bit longer and can be a bit more accurate but is slower and kicks harder. Both load fit inside a standard target wad, BUT the powder charges that are called for in the Lee instructions should be followed. Some people have simply used whatever powder charge they are using for their target loads, they get away with it BUT , (again that but word), they don't know their pressure just went way up.
I'll include a copy of the loading sheet that comes with the Lee mold so you can select a powder for them.
I also have a mold for the Lyman "shuttle cock" slug, it too is made to fit inside a target type wad. BUT it is a 1-1/8 ounce slug, slow, kicks like a Missouri mule, but hits like a freight train. I have a few of those made, IF I can find them.
UMmmmm, also I have a .390 round ball mold. It casts out at about 1 ounce, also fits inside a standard wad. Called "the punkin ball", it's what was used way back in the old paper black powder era for deer or real bad guys. Never got it to shoot well, kind of a curiosity.
I just positively located both of the Lee key slugs, counted them, I have 42 of the 1 ouncers close to 75 of the 7/8. Pick which weight you want and maybe someone else can get the others. Also if anybodies interested in the punkin balls,or the Lyman's let me know.
