What caliber to buy next?

[fsrmg1]

I would get a 22LR right off and if you're in an area where hunting with rimfires are prohibited, get a 22 Hornet like I did.

Looks like most agree that you need a smaller caliber/varmit rifle. I have a 204 Ruger that is great to shoot. I put a thumb hole stock on it since I have always wanted one. Here are a couple pictures:
First is with the new thumb hole stock and second is at 300 yards.

My sugestion is .275Rigby ( 7 x 57 Mauser ).
Witlold

Gotta go with Witold...again. 7x57 outstanding calibre. Mild recoil, good bullet selection. Can use it for most North American game large & small.

What do you want to hunt?

You know you could get a multi calibre rifle and you still would technically have a single rifle that can shoot more than one calibre e.g Thompson Dimension, Rossi, etc Just sayin'

6.5x55 if you want traditional or 50/90 sharps 1874 for something different
