Thank you both for the replies.
Most of my 12 gauge is Federal Field and Target. (The cheap low brass walmart bulk pack). I'm really stocked well on it, though I'm uncertain if there are many loads in there for them or specifically for low brass, but I think I'd like using them for a few reasons. They still get more than 1200 fps, and less kick, and should need less powder per pop, so all things considered, will be more stingy on components.
I was able to find this online from Federal, but I'm uncertain about the data and rather they are for the Federal Field and Target low brass, although it is listed by name and I think they are the first set of recipes (3 dram).
I do have some remmy xpress and Winchester super x for the 12's too, so I'm not married to the federal field and target, but I do have much more of it.
16 gauge I mainly have federal hi-shok and remmy game loads for it. And a full case of Rio that I picked up a while back because I got a good deal on it.
My buddy gave me two 25lb bags of 6 shot, so I'm set there for a while. Plus, #6 is my favorite hunting load anyway.
I am holding off on picking and ordering the primer/powder and wads until I get the manual so I can look through it and find the one that looks like it takes the least charge and powder that will work equally well for 12 and 16, though 20 and 410 may be in the future too but the 12/16 gauge will be first.
The biggest thing holding me off on the 410 is Lee doesn't sell an adapter for the loader, though I may get a Lanes brand 410 kit and do it by hand. Not really a big deal, at least for the small volume of 410 that I go through.
