From my count of 482 Savage 1899s in the three Scarcer Winchester calibers.
25-35 - 194 guns (7 SR + 3 SR TD = 10) 5.15% were short rifles
32-40 - 140 guns (16 SR + 6 SR TD = 22) 15.7% were short rifles
38.55 - 148 guns (11 SR + 4 SR TD = 15) 10.1% were short rifles
Overall 482 guns (34 SR + 13 SR TD = 47) 9.75% were short rifles
There is no way of verifying these percentages will transpose accurately to 303 and 30-30.
