I 100% agree I started reloading appr 30 years ago bought an RCBS Rochchucker Master Kit and I am still using it today I have probably loaded 50,000 rounds with it now and it is still as good as new.
Here are a couple tips...
For case/brass lube I recommend Hornady One Shot spray lube just stand your cases up in a tray shake the can to mix and spray let stand for a few minutes and your cases are ready to run thru your resizing die you do not even have to clean off the cases afterwards I do though only lube I have never had to worry about getting dents in the shoulder of the brass because to much lube was used.
Cleaning lube from cases put cases in plastic bucket spray laquer thinner onto them blow dry with compressed are especially the priomer pocket cleans out most of the primer crud. (use gloves)
Last step for loading 45-70's will be to crimp your cases I use RCBS die sets but only use Lee Factory Crimp dies for crimps they are super easy to use and will give you the best/most consistant crimp available, do not over crimp for top velocity jacketed bullet loads use a max crimp of 1 1/4 turn down adjustment cast can handle a heavier crimp = max 1 3/4 turn down but you will be just as happy with 1 1/4 turn adjustment.
Gun powder for the 45-70 = H322 yes I know others will recommend this or that powder and I have used almost everyone of them myself but there is one powder that is better than all the rest = H322 get it use it and tell anyone that suggests you use something else thanks but no thanks...
Never touch your primers with your fingers unless all oils have been removed from them nothing screws up reloading ammo more than having dead primers due to oil from your fingers and you will not know you screwed up until you try to fire the round.
Hope that helps and if when you are finally set up for reloading you would like some info on my H322 data that I use with 300gr to 550gr bullets pm me and I will share...
