Just getting back in to re loading , I used to re load 20+ years ago and no real training on it. I have a old Lee load all and want to make sure I am doing it safely. I want to load BB's for birds getting rid of varmint squirrels in the yard a little farther out. Any problem loading BB's in the old Lee press?
I reloaded shotshells since 1968 and have several progressive presses. I used to load out a keg of powder (3000 shells) in a single afternoon. In those days I reloaded for quality shells for well under 1/2 of new price. With the price of lead shot and Quality components, I save less than $1.00 (20%) a box over factory Remington Gun Clubs and Federals. I am not going to load for less than a dollar a box, especially since I can afford the extra $10 a week. I keep the equipment cleaned and oiled in storage just in case it is needed when things change. Say you get an entry level progressive like a MEC grabber. The press and a few accessories uses up a $400 bill pretty quick. It will take over 400 boxes (not counting time) to break even. Do you shoot that much? Even a single stage MEC is pushing $200 these days. I bought my first MEC jr singe stage for $29.00 at a department store.
That said, I know people who reload just because they like to. Technically, almost any shell can be reloaded. Can be does not mean they should or that they are trouble free. The problem is some of the foreign made shells have loose primer pockets with American primers. Some hulls are tapered,and some straight, you really need the right wad for the hull you are using. The old one piece compression formed Winchester AA hulls were great, the new multi piece AA hulls are problematic. Federals run a separate base wad, and are ok, (with the proper wad) but I only reload them once for use in a pump or semi auto. This is based on the fear of the base wad coming loose and left in the barrel, ruining the gun. With a break open, you can visually look down the barrel every shot and check for a clear barrel. I never had a wad jam, but I am not risking a gun (or my face) to save 2 pennys on a hull. The Remington STS, Nitro or Gun Club hulls are still pretty good.
If you are bound and determined, I'll be glad to help you with specific questions, or help you find the answers.
