I've got some advice on lead pots... Buy the largest one you possibly can. It's not that you need vast amounts of molten lead in the pot... It's that the more space between the top of the lead and the top of the pot... and also area to drop ingots into... the better. Also, if you are molding really large bullets, fast, having to load new ingots in drops the temperature a bit much. Results are more even if the temperature is kept more even... and having a larger molten lead supply pool helps you keep molding more constantly.

But... I don't know for certain but best I recall I've never bought a LUBRIZIZER locally. I bought a RCBS and heater for it new, somewhere on the internet, probably MidwayUSA. And I bought a really old Lyman on eBay. I have bought several presses locally, more kinds and quantity of Lees than I can even remember, one of which I eventually resold without ever using it because it just didn't ring my chimes, and most recently a really old Rockchucker... so old it was made by Ohaus instead of Blount, I believe. It's up in North Georgia, so I can't check that... and so is one of the Lees presses I don't remember exactly who I bought the Rockchucker from... but THAT may have been BWest.

But, as to shotgun shot... If you aren't so very fastidious about the minor considerations such as a swaged ball vs a molded ball with a sprue... you can make one size of buckshot in an EIGHTEEN-GANG Lee mold... if I recall right it is probably .36 cal., whatever caliber size ball works out in shotgun world to "triple aught". But the sizes available in round ball molds, if you are buying old ones off of eBay, is virtually infinite. You can find any size you want if you wait long enough, and the better brands typically don't leave much of a sprue. If you wait long enough and are lucky, you can probably also find a two-gang, three-gang, or maybe even several-more gang mold, and those speed up the process considerably. I'm particularly addicted to fine old Hensley and Gibbs molds or even moreso to the even older AND better George S. Hensley molds.

BUT... In PISTOL, for anything except extremely high-pressure rounds there is no need for particularly hard lead, and it's LUBRICATION not hardness that determines leading. The ONLY handgun leading problem I've ever had was with linotype in a Great War .450 Webley. It shredded that hard lead into myriads of thin splinters that literally coated both lands and groves in a dangling stalactite stalagmite forest of lead.

I've got a variety of muzzle stuffers from heavy duty to extremely light, that I hope to get around to giving a major workout to, some day... maybe after I'm so old I can only shoot by sense of smell and Braille.
