I know that there are a few 375 WCF fans here and I thought I'd pass along that Midway has Sierra .375 200 gr. FN bullets available.

Better price over here.
https://www.bullets.com/products/-375-Cal-375-200-Grain-FN-Bullets-Box-of-50/BL10276I've needed customer service from them due to receiving an item that had rusted (not their fault), and will say they delivered most excellently.
I prefer the 220 grain Hornady, but the 200 grain Sierra has worked well for me in the 375 Winchester in a Marlin 375 and a T/C Contender.
