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.

Packaging was the first thing I noticed. Brass was placed in it’s own slot is a plastic cartridge box than can be reused for loaded ammunition. Second was the very high quality of the the brass cases. Third was the prompt customer service that sped up the delivery process. 5 stars all the way around!

Very nice consistent brass. I got the Long version and while it is longer to the shoulder, it still doesn’t fit my chamber. Not a problem though. It’s about.010 short in mine. Still it’s very consistent. Holds 4/10’s grain less H2O than the W-W brass I’ve been using. Be sure to back down your powder charge when switching to this brass. Reloading 101.

Top notch

One thing that's so impressive is the packaging. Each cartridge case has its own protected slot to keep the brass in perfect condition. It definitely arrived better than most any brass I've ever ordered. This is the 7 mm Mag special long edition. And sure enough I took some measurements and the cases measured longer than normal brass. Which is great to deal with the extra stretch that belted cases generally end up with. Also the brass looks like it will need little prep. Maybe just a light chamfer.
