What caliber is a 1914 Winchester Model 1894 and where can you find ammunition for it?
You have to tell us what caliber it is. It should be marked on the left side of the barrel. The Model 1894 was chambered for almost every cartridge available, so depending on which one it is you may be able to find ammunition at WalMart and you may have to pay big dollars to get some from a specialty manufacturer like the Old West Scrounger.
