getting an opinion from the group

Everything but .40 will be more expensive to shoot, but they'll all be a lot of fun! I'd go either .357 Sig or 10mm.

 

I would go with .357 Sig.

 

.357 or 10mm because of the ballistics. I believe these will be better for a carbine.

 

I vote for the 10mm.

 

Also voting on the 10mm

 

Add me to the 10mm votes.

 

I would go with 40. you already have one, same ammo.

 

I'd vote for the 10!!

 

10mm because you could push some rounds over 2500fps

 

And over 600 ft/lbs of energy!!

 

Can you really get 2500 fps on a 10mm cartridge? Because that is rifle velocity, and some awesome stuff happens at rifle velocity in the world of ballistics. I think it is funny when people argue over a 9mm cartridge having 1200fps and a .45 having 900 some-odd fps. In reality that makes no difference, but 2500, now that can do something haha.

 

Oh yea I'd imagine so as the powder has more time to burn you already have some rounds that push 1100-1500fps out of a 4.6" glock 20 barrel and these carbine barrels are what 16-16.5" so I'd be guessing around an easy 2000-2500fps at that length!!!

 

135 Corbon is said to hit 1650 fps out of a 4.6" barrel... 16" I'm not sure, but I'd guess close to 2000 fps... As for energy, I've seen 625 out of a 4.6"... More from a rifle barrel I'd guess too....

 

The only auto loading pistol cartridge that I know of that can get even close to 2000fps out of a 4.6" barrel is a 9x25 Dillon. Double Tap has these at I believe 1975fps chronographed and pushing close to 880 ft/lbs behind it. It's basically a. 357sig but instead of a .40 case necked down to a 9, it's a 10mm case necked down to it. It's an awesome round.

 

Now if Glock only made a 9x25 Dillon....

 

Lone Wolf makes them for the 20/21, 29/30

 

I know what my next firearm related purchase is!!!

 

Haha right on man. It's as loud as a .223 though, no lie. I had to use foam plugs and over the ear at my local indoor range. I actually was asked to move to the rifle range because other people were complaining about the noise. Good stuff
