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.
