Not sure if this has come here yet. "The Rifle in America" by Philip B. Sharpe 1938. I have 1995 reprint by NRA for The firearms Classic Library so pages I mention will be for that edition. Pages 315 to 340 cover Savage thru 1938. Pretty good info although some is quoted from catalogs. Covers all Savage rifles in addition to 1895 - 99s. He has personal conversations (quoted) with Newton about his intentions for the .250 Savage cartridge (100 grain bullets) and Savage's different direction (3000 fps with 87 grain). A good read from almost 40 years before Murray's book.
