This brass is very thick, as others have stated. I reloaded all 500 pieces I got on a Dillion 550c. I ran them through a RCBs carbide sizer, seated with a RCBS seater, and crimped with a Lee factory crimp die. The only issue I ran into was with the powder funnel on the 550. due to the cases being thicker the powder funnel required quite a bit of effort to pull it out of every case. It didn't harm the cases or damage the press. It was about the same force as needed to size a case, just on the up stroke which is awkward. I have fired these loads in 3 different revolvers and a Model X lever gun and had no issue. FYI most of this brass has a .0125 wall thickness as apposed to most of my other brass having a .0110-.0115 wall.

I thought that I was losing my mind. I tried everything I could to make this brass work with my RCBS dies. I've reloaded thousands of rounds of 357 without problems. Finally, I read the previous review. It will not crimp and fit my case gauge! I did find a work around. hopefully it will help others?

I was happy to find this brass but I’m extremely disappointed with it. First off it is not ready to load, be sure to resize first. Secondly, this brass is so thick it is almost to big to use. I can’t believe what a horrible time I had using a lee factory crimp die. I tried the crimp on the bullet seating die and they wouldn’t even fit in my go/no go gauge. I would have much rather spoke to someone in person about this but unfortunately I can’t find a contact number. I have loaded thousands of pistol rounds in my years and never ran into this issue. I wont buy this brass again. Additionally, you can hardly read the weakly stamped head stamps.
Good value for the price
