Is this round good for anything, besides being a Major class rule-beater? Specifically, does it have the same reloading issues .357 Sig has, like difficulty in maintaining neck tension? ETA: Nothing makes you look like an idiot like mis-spelling Cor-Bon.... |

Specifically, does it have the same reloading issues .357 Sig has, like difficulty in maintaining neck tension? Yes, it has the neck tension issue, and it's possibly more pronounced than with the .357 Sig. I had a 1911 barrel and dies 15+ years ago. Some rounds would feed and fire just fine. Others would push the bullet back into the case and give severe over pressure signs. This was true with factory ammo and reloads both. Didn't make a difference if the brass was made from .44 ACP or was factory .400 Cor Bon brass. The neck was just too short to provide enough bullet tension. I couldn't crimp tight enough to make a difference. I eventually sold the barrel and dies and just bought a 10mm. |

Quoted: Spelling looks good to me.  You might not have known you can edit your thread title. See wasn't hard. I have considered getting a barrel in this caliber a couple of times, then something else comes up. But an interesting caliber to me. Now you got me quoting myself.

I haven't started reloading for it yet... Still need to pick up a barrel for the P220. I do, however, form all my SP .45 ACP brass into .400 Cor-Bon in anticipation. How do you do this? Do you need a case-forming die set, or can you just heat the case with a torch and jam it up in a .400 sizing die? I've been reloading for 20 years, but I've never messed with brass case modification..... |

The directions that came with my die set gave the following instructions (Hornady)
1. Run case into resizing die 2. Run case into neck flare die 3. Run it back into the resizing die The reasoning given is the first run through the resizing die will result in some crooked necks and the 2nd and 3rd step will straighten everything back out. I've found this to be the case. So, no forming dies necessary, just the regular die set, using the resizing die to reform the cases. |
