Cool, Critter. I’ve never loaded shotgun. I’ll be interested to watch your progress!
Walter I'm a bit stumped. I followed instructions on setting up press and selected 1 1/8 bushing for the shot and 141 for the powder which I used Green Dot. according to the chart it was supposed to measure out to 18.3 gr but I was getting 16 gr I changed to the max bushing which should of given me 19.3 but I get 16.9. I loaded a total of 10 5 slugs and 5 steel shot. Wondering if I should call Lee for why I'm not getting the amount of powder according to the charts

“Settle” the powder first to condense it a bit, since it’s a volumetric dispenser?

Just for info, Lee makes slug and buckshot aluminium moulds and are very affordable price.

So the cost of getting started with a "Lee Load All 2, in 12 gauge 2 3/4" and 3" shells, on sale $58.95,Lee 18 cavity buckshot mould $45.99, Lee 12 guage slug 7/8 oz mould $26.99. Total: $160 with tax and shipping costs.

The Lee has an output of 100-125 an hour. Not to bad of a cost to start loading 12 gauge. I didnt factor in the hulls,Wad's or shot cups, hull cutter, powder, primers, and whatever I missed.

If you wanted a better single stage press such as a "Mec Jr" thats about $209.99. Progressive Press is a grand.

When my uncle passed away my aunt gave me all of his shotshell reloading equipment. A Mec sizemaster in 12ga and a Mec jr in 20ga. At the time I was using an old Texan and a Lee shotshell loaders in the same two calibers. I will just say this the Mec is worth every penny. I would love to have a "blue " shotshell progressive but I don't shoot my shotguns enough to justify it. My uncle and I used to quail and dove hunt fanatically back in the day and he had great dogs. So we did a pile of shooting and we both reloaded to support our hunting addiction.

Critter, looking good. I load a bunch of 12 gauge birdshot for cowboy action shooting. I have only used the MEC and Hornady loaders. So, no experience with the Lee. I will say that my experience is that the bushing charts for the MEC and Hornady are super far off. I have found that you have to run the press and measure actual drops to see where you are. I am often 3 bushings different than the charts. Also, the charts in different sources are not the same. So, drop some powder and measure it. Adjust your bushings accordingly.
 
Just a little tip for roll crimps, Find something that is cone shaped and hollow, like a small funnel, or a cap to some container like cheese wiz maybe, anything will work, and set it down onto the hull and press lightly and give that hull just a very slight taper inwward, Then proceed to roll crimp and let it heat up with friction then push down on the drill or crank the lever on the press etc, but getting that beginning taper and letting it heat up with friction then pressing gives me factory results. Not all hulls even when they list the same length are the same length or will have the same stack height, Length of stack and hull length is critical and i recommend making your own cutter for slugs using a piece of scrap wood and a razorblade that way if you ever change hulls it will be easy to trim and get the proper stack height for the crimp. Judging by your pics it looks like to me that either your hull was trimmed just a hair to much, or that the stack height is a hair to tall. But overall for your first ones they look way better than my first ones did.

After carrying the shells in a pocket for a couple days hunting, I noticed powder leaking by my wads and around the slugs, not much but some. This also told me if just a tiny bit of powder is leaking out that its probably pretty easy for a tiny but of water to find its way in. I started using hot glue and then moved to melted candle wax, just a tiny amount around the outside of the front of the slug/wad, this helped seal the slug/wad from powder getting by, also kept the slug/wad more firmly seated, and gave me peace of mind knowing it was probably much more waterproof.

I know some people like to leave the tops open to see that it's a slug in that load, but I started using overshot cards (piece of cardboard) and a normal 8 pedal crimp and I can not tell any difference in accuracy at 25-50-100yds. And I find the traditional crimp is faster since its on my machine and I can just crimp and finish a shell all at one time instead of moving off my press for another operation.
 
I also tried overshot cards with roll crimps, and for some of the more stubborn hull / wad combos I was using it worked great and fixed little issues I had like fingers on the wad being to long, saved me from trimming lots of wads. And again I noticed no difference in accuracy from any other way of reloading for slugs as far as crimp goes.

I use wad filler cards also to bring the load of shot up to the top of the cup, then an overshot card if it still needs it. I still get a little twist sometimes, not a lot, but the MEC 600 Jr can be a pain to adjust that out so I just leave it. I need to get a good trimmer, lol.
