Hell no, there were 15 calibers in the 99.
303, 30-30, 38-55, 25-35, 32-40, 250-3000, 308, 375, 7mm-08, 358, 243, 284, 300 sav, 22 H.P., and the 22-250.
Got em all except for the 7mm-08 and the 243. Only reason I don't have a 243 is cause I can't stand the caliber. Had a 7400 in 243 and I swore I'd never spend a plug nickel on another one again.
