depends on how much time you have and how much money you want to spend, also factor in how consistant you want your loads
i know some ppl that love their progressive that have very consistant load and i know others that have very inconsistant loads... kinda guess it could be loader but who knows, i like my single stage sit down when bored and decap a ton of brass, then next night im bored i sit down and resize it all ( making sure i dont mix ) when i know ill be shooting ill sit down a hr or so a night and load as much as i can then shoot it up
right now 9mm lead 125 gr is $45 per 1000, 40sw/10mm 180 gr61.50 per 1000 flat point and .45 $67.50 200 gr per 1000 semi wad cutters, .357 .38 158 gr semi wad per 1000 is 54.75
thats with out shipping tho but over 10k there is 15% discount , so do the math on 9mm and its $38 area per 1000 plus part of shipping, i just paid $8 per 100 at fin
