9.3x57

Awesome report. I’m glad it’s shooting well. I’m wondering if with fireformed brass, it will alleviate the protruding primers.

I’m still waiting on my bolt to be sent back so I can shoot mine. Still looking for dies too.

I'm thinking that this like during the days of my making brass for 9x57. I do not think there is anything wrong with our rifles. We see basically the same diagrams of 9.3x57 from several sources. What was the original source of these numbers. I, for one, tend to buy into these numbers as coming down from the mountain carved in stone. The second thought is that we are dealing with a piece of machinery made that way by Huskqvarna. Here, the gun rules. Same with my old 9x57.

Right now we are dealing with little or no shoulder with what appears to be a longer head to cone measurement than in our diagrams. Also, we may be working at lower pressures causing protruding primers. Forming brass may be the answer.

This is what I'm kicking around right now. Trim a 30-06 neck and set should back in sizing die as the neck is expanded in Hornady dies. Make that formed case is a tight fit in the chamber. Fire form with fast powder and cream of wheat. Clean up case mouth. This is just a thought. I would like to get some input.

I have a few 8mm PPU cases that I may fire form. In the meantime the fired cases will be neck sized and reloaded. Those people who made those rifles were skilled craftsman building good rifles. After all that work they would not screw up chambers. The 9.3x57 is a neat cartridge.
