Looks like Buffalo Arms currently has .30 Remington in stock. Sadly, it's doubled in price since they last had it and they are using reformed brass (doesn't say what it's been reformed from). They are now using 150gr Hornady Interlock bullets instead of 170gr Core-Lokt bullets.
Current pricing before shipping...
20 rounds per box
1 box at $60
2 boxes at $57 each
5 boxes at $54 each
