Re: progressive reloading
Pinch your pennies, buy a used Dillon RL550. You can use Lee dies (big cost savings here) and can upgrade it as your finances and interest allow to include a case feeder, elevated mount, roller handle, several after-market additions too (like large knobs for adjusting the powder bar settings, primer catcher cup).
I loaded maybe 30 thousand rounds on one, sold it, bought an XL650 - have over 66k rounds through it. Used to own some subguns, still shoot several thousand round a year or more depending.
You'll want to look into places for bulk/surplus powder, brass, bulets like hi tech ammo, pats reloading, bartlett's reloading, scharch manufacturing, graf and sons, and there are many others.
Dillon's no-BS warranty is just that. I screwed up somehow, broke a handful of parts a couple weeks ago (piece came loose, I just applied too much force when I should have stopped) and I called Dillon. Parts came three days later, no charge. And I'm the second owner.
The cheaper makes, Lee and all the rest, just don't seem to stack up quality wise. I use Lee single stage reloaders for smaller volume reloads.
Think about it.
