I recently purchased 100 pieces of Hornady .300WinMag brass because I wanted something besides Remington and I couldn't wish hard enough to make Lapua crank out .300WinMag again!. I have used Remington alot in the past with other calibers, so I'm not griping about it.
I did the normal prep like you would with most brands, Lapua being the only exception that I can speak of. Others speak highly of Norma but I have heard it's softer than Lapua and the primer pockets become loose quicker than Lapua, especially after pushing the pressure envelope during load development. Only repeating what I have read, like I said, others speak highly of it.
I FL resized, trimmed all to the same OAL, chamfered the in/outside necks, deburred the flash-holes. Right now I'm fireforming/doing load development with 208gn A-Max's and RL26. After all have been shot once, I'll probably bump the shoulder back, chamfer again and anneal it. I'll probably have to adjust the load a little after this due to tighter neck tension.
Of the 100 that I received, two were lapped over in the neck region, rendering then totally useless. I sent this same picture to Hornady, to both help with their Quality Control and hopefully get two good pieces in return. Musta' fell on deaf ears, never got a response.
The majority of my lot of 98 weighs between 233.X to 236.x, with a couple of stragglers on both sides. That's not as tight as I would like it but it is what it is. I weigh them and then load/shoot them in ranges.
Hey, it's new, and it's shiney! but can't say it's any better than Big Green.
YMMV
