I have a Savage 99 in 300 serial 505xxx. I came up with 1949 but I'm not sure. I'm setting up some cast bullet loads and noticed the max overall length of 2.60 is to long. I'm new to 99 and don't want to get a bunch of rounds jammed in the rotary mag - looks like it would be a bugger to clear. Is they're a magic overall length that I'm missing, that will feed reliably in this rifle. I figured one of you gents might be kind enough to shed some lite.
