I haven't bought any equipment yet and I realize this isn't the best time to start and components are hard to find and expensive.

So I'm just pre-planning here.

I'm interested in loading pistol calibers I like that are expensive even in the best of times.

1. .32 h&r Magnum (fmj bullets preferred. And it's always expensive)

2. 7.65×17 mm / .32 acp (to load a little hotter like Fiocchi and S&B do)

3. .44 Russian. (It's just fun to shoot. Always expensive just like .44 Special. Like the more efficient, short cases that eject easier than .44 Special.

4. .38 ACP / Super, if I ever get a .38 Super 1911 pistol.

5. .45 GAP. Acquiring one and ammo was never widespread available.

I'd like to know if any of these are particularly troublesome to load or reload.

And, do they have anything in common? For example; can they share primers or powders?

I'm just trying to learn everything I can before I buy anything. It's just what I do before I jump in.

Thanks.
