Just bought 1k of these in 124gr. 9mm flat point and I'm wondering just how fast I can push them?
I'll be shooting them in a 38 Super.
 
Reason I ask is because I've heard plated bullet load data should be comparable to cast bullets.
Also read plated bullets should not exceed 1200 fps.
 
Are they back in production? I used to use them all the time, even WAY back when they were called Western NV/West Coast Bullet. Then they went BK, and ownership transferred - but I never heard if production resumed.
 
Same here. I shot about 20K of them but since they went bankrupt acouple of years ago I haven’t dared order from them.

Extreme is one of the brands I find at my local Cabelas, for whatever that's worth. I actually like them better than Berrys.
 
I've used Titegroup 3.9grs, but it was for my wife and she doesn't like heavier loads, also AA#7 6.8grs and HP-38 4.2grs. All with 124 CPFP from eXtreme in a 9mm. Maybe you can compare the pressures for what you're shooting?
 
X-tremes were my go to plated bullets for 9mm and 45 ACP for a long time. But after their reorg, they priced themselves out of my personal market with their shipping costs. I’m getting jacketed bullets delivered cheaper. But, nowadays, you pretty much take what you can get. Their recommended velocities were never a problem for me as I never approached their speed limit anyway.
 
Follow the manufacturer's max velocity and don't over "crimp"! These will disintegrate when pushed and especially if accepted reloading protocols are not followed! As an RO/RSO standing behind some shooters I've seen first hand bullets separate but I can't say for sure what caused the separation. Except in one case where I inspected the ammo and saw evidence of over crimping.

I have current and pre B/K Extreme 9mm 124 grain plated R/N. They are capable of banging 8" steel at 100 yards "all day long" out of my 16" PPC!

The last order this month got here pretty fast!

For pushing 38 Super at higher velocities get jacketed!

Smiles,

Those bullets are .355"diameter. Supers are commonly .356". Have you slugged your barrel?

It probably doesn't matter because:

a) 9mm and 38 Super have the same SAAMI .355 + .004 groove diameter specifications.

b) Few 9mm and 38 Super barrels measure .355. Of the dozen or so 9mm barrels I've slugged, only 2 were less than .356.

Their website says .355”, but, FWIW, I have measured handfuls of X-treme 124gr HPs, FPs and heavy plated RNs and they all were over .355”, averaging .3555”. Very consistent and very good bullets IMO.
 
A I've been lead to believe modern 38 Super barrels are made to 9mm spec's.
 
"Bullet/Load Info"
From the X-Treme website:
HP = Hollow Point
FP = Flat Point
HPCB = Heavy Plate Concave Base
RN = Round Nose
RNFP = Round Nose Flat Point
SWC = Semi Wad Cutter
WC = Wad Cutter

All Hollow Points are Heavy Plate Concave Base but are not designed to be used as a defense round.

Load Info
Our Copper Plated Bullets can be run at mid-range jacketed velocities or higher end lead velocities. We recommend keeping velocities to less than 1500 FPS (Feet Per Second) and using only a light taper crimp

Any velocities over 1200 FPS we recommend either our Heavy Plate Concave Base or Hollow Point products for superior accuracy. We recommend keeping velocities to less than 1500 FPS (Feet Per Second) and using only a light taper crimp
