Used lots of Bertram brass; the later ones are good. 3000 fps with 650 grainer? wow, I had no idea it was that fast. What action do you build them on? That head diameter has got to be, well, big.

I know you've been working on this project for a while now but I haven't keep up with it. I've got to ask, what type of rifle are you launching 650grn bullets at 3,000fps from and how big an ol' boy are ya? A man that could hold up to something that powerful that presumably generates that much recoil is bound to be a fairly tough individual because that's got to be a pretty rough ride once the hammer falls!
Wow!! Ed has stayed the course on this one. He tried a 585 on the Gibbs case, even swaged a belt. It works, but this will be a much better option. Dies and brass available.
