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.

Very uniform including neck thickness. Turned necks to 0.0145" and ALL 100 case necks cleaned up 100%. Great product at a very reasonable price.

This brass is very consistent in both weight and appearance. The necks measure .0165 to 0170 in thickness and they turned nicely. The primer pockets are nice an uniform. I have fired it twice and so far things are look good. I'm ordering more!
