it takes 30 30 ammo Winchester cartridges retained the .30 W.C.F. designation on their headstamps and advertising up until about 1946 after which they changed their nomenclature to . 30-30. Interestingly, today it's called the . 30-30 Winchester but it was Marlin & U.M.C. that gave it that designation here https://ammoseek.com/ammo/30-30-winchester

30wcf is the same cartridge as 30-30 as others have said just changed the name. Hope this helps.

Vito, you want 30-30 Winchester ammo, all currently out of stock at Bud's. budsgunshop.com/search.php/type/Ammunition/caliber/10000552/sort/per-round-asc

Vito, The 30 WCF and 30-30 Win are the same; they simply changed the name. Cheers and stay safe!
