I reload:
Pistol
9x18 Mak
9mm
.45 ACP
Rifle
.223
7.62x39
.303 British
7.5mm Swiss
.30-06
.30-30
I don't reload 7.62x54r yet for the Mosins. Mosins, other than my Finn M39 are not accurate enough to see much benefit to reloading and .312/.313 bullets are expensive. I have quite a few spam cans of Bulgarian Silvertip, Ukranian ammo that I paid about .14 per round for years ago put away, even a few thousand of the Czech low recoil training ammo so I am fine as far as ammo to shoot, I just can't see the logic to reloading Mosin food that is two or three times as expensive as milsurp. I like reloading 7.62x39 but my AK throws the brass so far, it is frustrating trying to keep track of expensive and hard to find 7.62x39 brass. Same story with my Tokarev, 7.62x25 would be a great caliber to reload but the pistol flings the brass really far so I am on the fence on reloading for it so far. I sold off my 8mm Mausers for the same reason, have you ever priced out .323 bullets? Ridiculous and 8mm ammo in general is pretty difficult to find at reasonable costs, even for Romanian surplus.
I am thinking about buying my first distance rifle, a Ruger Precision Rifle in 6.5 Creedmore, that would be my first attempt at loading precision, long range ammo, which could be fun. Shotgun, I shoot clays, there is basically no savings over reloading compared to cheap Walmart shotgun ammo. If I hunted or had gauges other than 12 and 20, I would reload shotgun but all I do with shotguns in shoot clays so it's just not worth it. Sure, you can make slightly more accurate loads but at the same price as you pay for Winchester Super Targets from Walmart. If I am realizing no cost savings, my time is too valuable.
So in a nutshell, I reload most of my calibers, but not all.
