Heavy subsonic 9mm loads
I have been having good success with the Rainier 147gr FMJ and JHP with 3.6gr of 231 out of my suppressed 10.5" Colt. I bought some 158gr TTI Armory subsonic loads, and like the increased thump on the receiving end.
Does anyone have any experience with swaging jacketed bullets down a little bit? There are a lot of heavy .357" bullets out there, but nothing over 147gr in .355. I think I want to try swaging, but know nothing about it other than 'it's possible.' Any tips? |

They'll swage themselves going down the bore.
Slug your barrel, and see what you're workin' with. Bet your groove diameter is .3565 or more, making your gun a .357 anyway. You're prolly gonna have to seat and crimp in different steps, worst case scenario, use a LEE carbide factory crimp die. What kind of press are you using?

Either that, or you could use .38 super bullets....

A Dillon 1050. My barrel is a chrome Colt 635 SMG barrel, I suppose I should slug it. Firing oversized jacketed bullets in a high pressure load is a ticket to trouble. If they were lead I might consider it, but I won't fire unjacketed bullets through my suppressor.
What diameter are Super bullets? |

If you develop the load using the larger bullets the pressure will be taken into account during load development.
One problem you may encounter is the need to use a slower powder to get the velocity you want with the larger bullets. Very fast powders can deliver poor velocity with the extra work of swaging the bullet down to size. A slower powder often works better. |
