The rock chucker will be fine. It should work well for anything short of the largest mags and will still work well for pistols. Ya just need to change shell holders and dies.
I think the Redding presses are slightly better, but I am not dissapointed in my recent purchase of the rockchucker IV. I would go w/ a set like the rcbs or similar unless you want to piece stuff together. Starting out w/ a balance beam scale is fine, I prefer electronic but ya gotta start somewhere and if 200 scares you for the starter kit... you will not like the price of electronic scales.
Dies, dial calaper, shell holders, priming tool, case lube, casing trays for loading, powder funnel, press, and a good book are the bare essentials IMHO. The following will be nice: powder dispenser (lee is just fine), VLD case mouth deburring tool, Case trimmer (Lee works just fine and is cheap), Digital scale, inside primer pocket deburring tool, outside neck deburring tool (must deburr necks when you trim cases!)
start will the lowest charge and work up with caution and don't go beyond published levels. Hodgdon powders are nice and hodgdon gives lots of information on their website.
ALways use data w/ the exact same powder, similar primer, and same bullet weight that you are using.... I digress lol! ya probably know the basics so I'll shut up unless ya ask more Q's in the future.
By the way... WELCOME to the wonderfully addicting hobby of handloading. Be prepared to spend lots of time and money learning and upgrading. Just like everything else that's fun! lol!
