Winchester Brass 300 Winchester Mag Unprimed Bag of 50
Due to the packaging and shipping process, case necks are often slightly dinged or bent and need to be rounded up and sized to give proper neck tension. New and/or fired cases must be full-length resized or have the expander ball of the sizing die run through the case neck prior to loading.

300 Winchester Magnum brass.

By Wayne S. on Feb 13, 2019
I found the 300 Winchester Magnum brass to be of good quality. It sized well and required very little trimming to make proper length. The flash holes required very little reaming. The primer pockets did require uniforming.
