While you might buy a rifle from Newton's Buffalo Arms Company, or a .280 Ross (if you had the money), there were very few sporting bolt actions being produced in the US in that period. Developments like the .357 and .44 Magnums were far in the future. The great Model 70 Winchester wasn't developed yet. Even many out-of-production classics like the Colt Woodsman and the Winchester Model 52 weren't yet developed.
The hot loading of .38 Specials, .44's and .45 Colts was certainly underway during that period. THis is what led to the formal adoption of magnum catridges.
The "great Model 70 Winchester" is for all intents and purposes a sporterized Mauser '98. It was a revelation for American shooters to have a high-quality Mauser sporter at an affordable price, but it was hardly a new design.
The Colt Woodsman begain productin in 1915, so again we are in the golden age.
And the Winchester Model 52 was developed towards the end of WWI and was introduced in 1919, right at the tail end of the golden age.
I rest my case
