I’ve been reloading for 30 yrs, 19 of those were with a old Lyman cast iron “C” press (I still have it) Bought from a co-worker with dies, scale, and a few other odd and ends for $75 it served me well. In around 2000 I went progressive, and bought a Dillon SDB…WOW! Why did’nt I do this sooner?I was loading .44mag, .38/.357 on it,running alot of high quality rounds off the press in a 1/4 the time it would take with a single stage. but at the time, my shooting started to change as I was going to semi auto pistols, and rifles,(.45,9mm, 30-06-M1 Garand, .223-AR) It became clear That I had made a basic mistake, and did’nt buy enough press, I ended up buying a 550,and have been using it ever since. I agree there’s nothing wrong with starting with a progressive, and with the 550 you can easily run one round at a time and get the feel of how everything is supposed to work, in fact, when changing calibers, I still run one or two through at a time to check powder charge, OAL, crimp, and make any adjustments before I start filling primer tubes up.I’d highly reccommend a 550, it is’nt as fast as,say a 650, but reloading is’nt a race either, I can still load 100rnds of pistol ammo (9mm,.45) in about 10 minutes, That’s fine with me. Granted, rifle ammo will take longer, but there’s more brass prep invloved as well, In 11yrs I’ve used the 550, and probably loaded 10’s of thousands of rounds on it ,I’ve yet to have anything break, They work and work well. OP; you’re doing the right thing, reading up on the subject,Reloading is’nt THAT hard, it goes alot easier when you have quality equiptment to start with, Do your research, Do check out Dillon and others before you buy, Go over to www.brianenos.com and click on the “forums” tab, They have forums for Dillon presses and non dillon presses as well, lots of info, also check out the reloading section, these are caliber specific forums, again, lots of info. The day you start reloading is the day you start saving $$
