These are all reloads but brass, primers and powder is good. I wouldn't shoot someone elses reloads in my gun and don't expect anyone to shoot these in theirs.

These are hard to come by and I sold my own .300 a few years ago, so don't need them.

All four boxes for $25

Also have a box of 358 Winchester Magnum Super-X 200gr. Silvertip for sale. Not pictured.

The 3 boxes of 300 Weatherby Magnum are loaded with 200 grain Nosler Partition, 72 grains IMR 4350 powder and CCI 250 primers. Case length 2.815. 

1 box is 10 nickel cases with 180 grain Nosler Partition and 9 brass 200 grain Nosler Partition.
