Just picked up a old Savage 99 in fair condition. As far as I can tell it is a 1907 model, chambered in 303 Savage with a rotary mag. It has a marble arms peep sight tang mounted. It also appears rather on the old side,
Shells are way expensive for this thing, but dies can still be bought for reloading.

I saw some thing once that you could use 30 30 brass to make brass for the 303 but I just can't remember where I seen that at.

I've got an old (1961) cartridge conversion book that recommends using 30/40 brass,


" turn rim down to .505" diameter; Swage head to .442" diameter; Trim to 2.01 length; Size full length; Use .308" bullets. " from 'Cartridge Conversions' by Nonte.

Don't know much about the book or author, but it came out of old-school gunsmith's shop from the '50's thru 70's.

Brass and cartridges are available from internet sources, (google 303 savage). Chamber pressures are mild so reloaded brass should last a long time. You can load cast bullets for short range small game loads and cheap practice. Jacketed .308 bullets for larger game. It was developed by Savage to compete with the .30-30., popular at the time. Even though it's called the .303, it takes .308 cal. bullets. A bit of marketing from Savage I suspect.

From the high road archives
".30-30 brass is ~0.04" smaller at the head than .303 Savage and you'd likely get split cases that could damage the rifle's chamber or worse. According to Ken Howell's book Custom Cartridges you can form cases from .220 Swift cases by fireforming with an inert filler (corn meal) and a fast pistol powder. Then back off the .303 Savage sizing die so that the cases headspace on the formed cases shoulder instead of the rim. Trim them to length, deburr
