[geezer mode] 45-70 used to be relatively cheap to reload. Remington used to sell component bullets, both the 400 gr soft points and the 300 gr hollowpoints for around $16-$18/100. I also used to be able to get 5 gallon buckets of wheel weights for free from about any tire shop, and would cast my own to make it all pretty cheap. I bought factory ammo in the beginning (think it was around $7.50/box), so had a couple hundred rounds of brass going, which so far hasnt worn out, as well as a couple hundred new brass ive never needed to break into.
I started out with a Lee Loader, then got a Lyman 310 tool, both only neck size, part of the reason brass lasts so long. RCBS bench dies make good ammo, but arent strictly required to make decent ammo. [/geezer mode]
