I found this on another forum, to help give some insight on the 99's spitzer troubles.
" I can provide a reason for the round-nose bullet - shorter bullet nose length. The Savage 99 magazine is very sensitive to cartridge overall length, and will jam if the cartridge is even slightly longer than standard . If the cartridge is loaded with heavier spitzer-type bullets, the intersection of the bullet’s ogive and the cylindrical body will be below the case mouth at the maximum cartridge OAL. I have found that about the heaviest spitzer bullet I can use in reloading for the .303 Savage is 130 grains for that reason, and I usually use 125 grain or 110 grain spitzer bullets when I don’t use 150 or 170 grain RN bullets as used in the .30-30. Within the useful hunting range of the .303 Savage, a round-nose bullet is fully adequate. The original .303 Savage load using the 190 grain RN bullet had a well-founded reputation in its day for its penetrating capabilities on large game. Otherwise, it’s the ballistic twin of the .30-30."
