357sig a Trip down the Rabbit Hole

[MikedaddyH]

Ok , It all started back in 2012, I couldn't find any 357sig at my LGS or any other LGS 's in the area. So I started reloading it. My nephew and I were shooting my brothers G31 and I started reloading range ammo for it. Projo's were hard to get so 9mm (.355"dia) and 38 (.357"dia) were experimented with. Everything feed and shot well but it was just range ammo.
About 4 years later I got a G31 then a G32 followed by a G35 in 357sig. And down the Rabbit Hole I fell. Pulled the rope in as well ! Since then I have made 4 loads that are kinda special. 115gr XTP , 125gr XTP , 125grFMJ and a 142grFMJ. There is a 3 page thread on 308forum in the reloading section. If one needs more information on it. My favorite is a 125gr load chrono'ed at 1615 fps and accurate to 450yards on a steel target , off the top of a mountain ! I sh!t you not, we were shooting high angle on steel at 275 ,325 , 375. & 450 yards. When we were done I broke out with a brand new G31 with plastic sights and 4 mags of some spicy "warm" rounds. All 4 of us shot and hit steel with that Glock.
I have also developed a142gr projo load that's spicy but not hot .Chorno'ed at 1505 to 1550 fps depending on with powder I use , Longshot or 800X.
I have also formed 357sig cases from 40S&W cases, and yes they work just fine !!!
Now I have an ARP in 357sig. There is no light at the end of this tunnel.

The G31 used from the top of the mountain.

Think how much kooler a 9x25 Dillon could be.

Ruger used to sell a P89 with optional 30 Mauser (7.62x25 Tokarev) barrel. Oddly enough, I had a Chinese Tok with an optional 9mm barrel. Used the same mags as the Tok for 9mm. Necked-down cartridge like 357Sig, had quite a "crack" out of the muzzle.

I shot a G29 with the Dillon barrel. It's wasn't particularly fun to shoot. A G20 frame should be alright.

The .30 Luger is not the .30 mauser.
Ruger sold a 9mm/30 luger combo

You are correct, my bad. 30 Luger is 7.65x21, 30 Mauser is 7.63x25, Tokarev is 7.62x25... 30 M can be fired out of a Tok, but Tok 7.62 should not be fired out of a Mauser 30.

It's all good.
The .30 luger is a piss cutter too.

For the Dillon cartridge, I bought a barrel in it for the 10mm pf45 build and reamed a 9mm barrel for my tanfo stock 3 to take it.
10mm stock 3.

I really need a .40super as well.

Just purchased a g20 357sig conversion barrel.
Sprinta precision. $99 and I think they still have them for that much.
Not combat armory garbage bore barrel either.
Still debating if I am going to ream it.

I have used about a dozen Sprinta barrels and about 8 of their for slides.
I have been looking at a G20L Dillion barrel from Spectra for $138..
