357SIG Underwood Ammo

Post by ThawMyTongue » Mon Nov 03, 2014 1:09 pm

I have a 357SIG conversion barrel for my XDm40 and have enjoyed shooting the caliber for a few years now. Due to the ammo being not as available as others I have been mostly shooting WWB and Gold Dot ammo. A few months ago I ordered a few hundred rounds from Underwood knowing their reputation for "hot" rounds. I haven't gotten around to function checking the ammo until yesterday...

**** **** this stuff is hot! I had ripped though a mag of WWB first so I would have a benchmark and then switched to the Underwood stuff. There is definitely more flash though I wouldn't say it has more kick... More like more "push". It just feels powerful. This actually feels like I am shooting a clone of the 357Mag out of a semi-auto (exactly what the creators of the caliber intended).

I might have to sample some of Underwood's other offerings. It actually makes me want to pick up something chambered in 10mm. :D

Are you watching for pressure signs?

Yup, no flattening of the primers, no mangled brass, gun runs like a top.

I'm so relieved that you didn't answer my question with 'What are pressure signs?' :lol:

What? You mean the firing pin isn't supposed to punch a hole in the primer and the brass isn't supposed to bulge?? :mrgreen:

Sneak's, I think you are comparing apples to applesauce. I think they will be close but different. The 357 Sig should cause a deeper wound while the 135 40 make a larger shallower wound. My only concern with the 135 - 40 would be enough penetration for your big mac fueled neighbor seeking Twinkies.

Romellio:

Welcome Aboard!

(I see you've hit on an old thread. Everybody does that; not to worry.)

There's a sticky at viewtopic.php?f=6&t=10097 that you should have a look at, but it's not mandatory, and may cause sleep. Or worse....

Otherwise, Enjoy!

Romellio:

Very interesting.... Your second post is identical to your first, except for a link to a web site selling weapons that may be illegal in OH....

I'm starting to get the feel that the URL is your only purpose for being here....

Stu
