through the exercise recently, and still don't have everything I "need" I will take an estimated stab at my present outlay.
I have not pulled the handle yet, that is to say I have not loaded a single round. I'm not in any hurry, it has taken me two years of "putzing" and going it alone to get everything I needed. Much of this is due to my lack of diligence, the marketplace (scarcity/leadtime) of components and raw materials and recent demand increase in loading/reloading interest. Thanks Mr. President.

Based on a Hornady LnL Progressive.
Necessary items to reload: .45, .38/357, .223.

I still need to spend another $100 or there abouts for a tumbler and media for same. Probably another $100 in odds and ends.

I will hazard a guess....$1000 to 1200. in round numbers.
I have probably enough materials to do 500-1000 rounds of said rounds.

Not bad for a hobby that gives back.

I did it to learn something new.
Something to do now that I have a basement and winters.
Good investment in today's social condition.

Hornady could do themselves a favor by including a list of things that are:
Necessary to continue after the purchase of the basic press.
Nicities, but not necessary.
Luxuries.

I spoke to a factory representative who sent me a list of things I needed. Nice since it took me a year of stumbling around myself to get to that point.

There are some good videos on You Tube, take them with a grain of salt of course, but most of the people know what they are doing.
