cause hydraulic shock? Or just a lot of trauma?

Dependent on bullet being used, the velocity at impact...some bullets may over expand catastrophically, some may zip through, some may perform great.  Lighter usually faster, Heavier carry more mass deeper.
Everything is relative to what you might see performance wise.  

Ok, it's the Uw 9x25 Dillon 124 XTP out of the G29.

Probably get 1140-1150 fps for 600+ fpe.

The 124 grain XTP performance envelope extends up to 1400 fps.

So, this should be good to go.  Solid hollow-point design being fired within the correct velocity envelope and delivering over 1100 fps and 600 lb-ft.  This checks all the boxes for reliable hydrostatic shock.

Wow, wicked.

Looks like I posted the velocity of the Uw 10mm 200 XTP out of the G29. For the 9x25 Dillon out of the G29 it is 1500+ fps.

I would say that it is one of the few handgun calibers capable of experiencing hydro-static shock as some smaller rifles with top loadings.

The cartridage has some darn respectable velocity numbers with lighter bullets for sure.

I have always had a affinity toward it but never made the jump. BUT I did just buy a 357 SIG barrel for the G23... 

CW

Since I have a 10mm, I bought a necked down 10mm rather than a necked down 40sw.

At 1500+ the bullet may grenade rather than expand and penetrate.

The 9X25 generates velocities such that you may be well served with bullets without a hollow point.  A truncated cone design in a 100 grain at 1700-1800 fps would do pretty well terminally without expanding.

And, of course, there are all the 357 Magnum bullets in the 90-110 grain range that should handle these velocities too.

Yep this is what's left of the 0.356" 121gr ZERO JHP from the 9x25 @ 1550 fps Glock 29 3.78".   


Same load makes 1640 fps from the S&W 5" bbl.

Is that from the gel tests?

Well, my two 9X25 barrels should be here by end of week.  Along with a set of reloading dies.

Barrels for my G29 and G20 arrived last night.  Drop right in.

Dies arrive today.

Shadow, when forming brass do you lube the case?  When I form rifle brass I always put a bit of Imperial sizing wax on each one.  But those are steel dies, not carbide.  Seems like I would probably want to, but wondered about your experience.

I have used the Dillon Carbide dies without any lube for the 10mm to 9x25 sizing.  They have dual carbide sizing sections.  Imperial Sizing Die Wax is great stuff, I did use it recently when I was sizing the 6.8 brass for the shot shells to be on the safe side with the thicker brass.

The neck will look a little funny until they are run through the expander process.

You will need a neck expander plug to straighten and uniform the new necks.  I use my RCBS 9mm expander (that plug is longer than others especially the powder throught types) by raising that die 1/4" using two 1/8" spacers so I don't have to adjust the 9mm expander die adjustment.  It provides just enough expansion to accept the bullet's base for straight seating.

Here is a picture that explains why the 9mm expander die setting doesn't need to be adjusted...



BTW when doing 357Sig I only use one spacer for the same reason...

sqlbullet, also when setting the Sizer die, stop short of the shell holder as it can over size and set the shoulder too far back.
Ease the die down in stages of small increments 1/16 of a turn.
Check in the chamber trying for 0.000" (Flush) but no more than 0.002" (below)
