I think.300 Savage was more equivalent to the 30-30.
Actually, the .300 Savage is MUCH more powerful than the.30-30 WCF in every standard load & at any distance.
The .300 SAV only SLIGHTLY inferior in power to the 7.62x51NATO (AKA: .308WCF), according to the former chief engineer at Springfield Arsenal. = His office admitted (about a decade ago) that the reason that the USA did NOT just use the .300 SAV unchanged was that they did not wish to pay royalties to the original designer.
