My semi auto 357 Magnum

[my_old_glock]

I put a 357 sig in the barrel and it centers up. I think I can shoot 357 sig from the 9x25 barrel just like 40's from the 10mm barrel.

I don't think it will work. I am guessing the case will open up to 10mm case diameter before the bullet can move into the bore. Once the case no longer can hold the bullet in line with the barrel, the bullet will just flop around in the chamber, and may eventually get forced into the bore sideways.

Place an empty 40S&W case next to an empty 9x25 Dillon case. If the end of the 40 case does not reach the necked down part of the 9x25 case, I doubt a 357 SIG case, which is slightly longer, will hold the bullet.

Ok, a 357 SIG is basically a .40 cal necked down to 9mm, You even use the same mags and springs, only a barrel swap is required. how about a Super Sig, with a 10mm necked down to 9mm? Oh wait, that is basically a 9X25 Dillon.
...

357 Long Neck (Kayan). You can use heavy cast bullets.

I wrote an article on 357 SIG, and in my research I found its based off the 10mm.The 357 SIG has 23mm brass, the 40 uses 22mm.

Edit:I see you mentioned that too, I missed it the first time around.

My dumb ass has already fired a 357Sig in it, and my son was supposed to keep his eyes on the brass, but lost it. I haven't found it yet, my 29 has never behaved as well as my Ruger P93DC , it's mischievous and throws brass every which way, my Ruger will pile them up neatly, about 10 feet over, at a 45 degree angle from me.

I usually recover 4 to 5 out of 11 fired.

From what I can see in the picture, it looks like the 357 SIG brass will still hold the bullet in line with the bore if it is fired in a 9x25 Dillon barrel.

Did the bullet come close to what you were aiming at?

It sure did. Just not as loud as the 9x25.
