bigtad,
I used By's idea for my .224 MBOC. We emailed serval times before I decided what I was going to do. I took 200 .264 Winchester cases and made them into the above design. The neck is 7/16" with sorta his shoulder design. The case isd shortened to 2 5/16". I don't remember, but I think it hits 4,300 with a 55 grain Nosler. The temporary rifle is a 26" Savage.
After I get the bugs worked out and all the brass fire formed, MOA is going to build one with a 30" Pac-Nor. I think he will use his own action. (He made the action for my .257 Weatherby.) I think it hold 68 grains of water to the bottom of the neck. His 5X35 is not length, but 5mm X 35 grains of water.
