Heck, you're talking about my main rifle battery here. I'm really not that old. 25-20WCF Marlin '94 (1906) 250-3000 M99R (1953) 250 Sav. Ruger M77 Tang Safety Pre-Warning Yea I know it's the same cartridge, just the way they're marked 257 Roberts M77 MkII
Son runs a 300 Sav. M99EG (1954)
They may be old but they'll do anything I need doing up to elk size game.
