All, just an FYI: I came a cross a Montana ammo maker that seems to produce a lot of calibers, incl some that are in “limited” production, e.g., they make 270 WSM, 6.8 Western, 7mm PRC, 7mm STW, 300 Savage, 375 & 416 Ruger, 458 Lott, and seven of the Weatherby calibers.
Disclaimer: I’m not associated with this company. I’ve never even bought from them. The ammo is not necessarily cheap and not necessarily in stock on a given day…but I thought I’d share since I just noticed that they sell some calibers that are generally hard to find.
EDIT: Silly me - i forgot to name the company…
Choice Ammunition
I’ve had very good luck with choice ammunition. Didn’t realize that you were talking about when you first posted. I tend to find that it is more accurate and has much better es/sd values then what you get from most Factory stuff. Yes, it is quite expensive however.
Managed to take a pretty nice Kansas 10-pointer last season with some of their stuff.
