Correct me if I'm wrong, but didn't hi vel ammo come into existence in 1932? If that was the case then categorically anything made before 1933 was intended for std vel stuff. There are a few rifles from that era that had/have the moxie for hi speed stuff but they are bolt action guns like the Winchester 52, 1922 Springfield, and various stout single shots and surely some of the better quality 1920's pumps from Sav/Win/Rem. (I routinely fire HS ammo in my 1927 Rem 12C with no visual ill effects. Maybe I shouldn't.) Did Savage give a retro blessing for pre-existing 1919s, 23s, and Model 25 pumps after hi speed ammo came out, possibly through their advertising? I wonder if any of the Big 3 made radical changes to their metallurgy to accommodate the new ammo?
