I am sending this out there to the Gods who make Wild Cats…
.357 Sig is a cool cartridge… but they failed!
What we need is a reboot…
We need a 10mm necked down to 9mm
I bet you could get some crazy speed out of THAT!
Run 124 grain probably at 1700 feet per second…
Run a 90 grain solid copper past 2000 feet per second! !
The glock 20 would just need a barrel swap. 3:grin:
this…might just do
It is crazy enough… it might just work!!!
lead and brass, both available, load data, I imagine stick with 10mm…
so, a little chamber bore on a 9mm barrel?
Think I’d still want the SAO version
I want a G40 chambered in it… 6 inch barrel
Cool!!! Haahahhahaa
Done!
I have some 4140 steel in the shop, but I have little time to make a reamer. That’s your job rogue!
Yeah, I do not have the tooling to make a remer.
So what you would do (the cheap way) is buy a normal 10mm reamer, chuck it in a C-5 collet fixture. Mount that on a lathe with a grinding fixture, or a surface grinder.
The diameter you would shoot for would obviously be for 9mm. The end of the chamber of the reamer would mirror a .357sig reamer.
It is also possible that you could modify a 357sig reamer and just cut a little deeper into the barrel.
The most difficult part would be making a standardized measurements and a go, no-go gauge. After that we test chamber pressures and start load development.
Bwwwahahahhahaa
You load it till the primer is flattened out then back it off 1/2 a grain… right?
Well I see we’re going for the high numbers! I will be wearing a face shield and welding gloves for this one!
Speaking of that… I test fire that M1 Carbine converted to 45 win mag to day. Hahhaha this will be epic.
That’s awesome! I can’t wait for the range report!
9x25 Dillon is your answer and what I’m about to do on a Glock 20.
Out of the factory 4.6" barrel you’ll not see much of a difference from the 5.47". Probably just within the difference between one round and the next.
