Faster than a speeding Berrys!!

[Lead hammer]

What happens if you shoot Berrys bullets past 1250fps?? Bullet comes apart and won't group? Gun blows up? Turns into a diamond??
Ran some through my GP because of a mix up during load development. I was only testing velocity, so did not notice any grouping issues.

I don't consider speed when I load them, but the only gun I have that can shoot them fast would be my 357mag. I should load some 124gr ones with h110.

I haven't noticed any issues.

Thanks Spawn, I like to find my max, and work backwards for accuracy. This mix up sucks as my load data I just collected is now incorrect for the bullet I intend to shoot. (CamPro)

 

[Easy 9mm]

I've had Berry's 124gr plated round nose that did 1060 fps out of one of my pistols. When I tried them in my JR carbine, they were flying at 1350 fps. No disintegration, KB, loss in accuracy (~2 MOA at 100 yards) and no diamonds. Won't be using that load with the carbine anymore though. Pretty flat primers.

How bad of a load mix up are we talking? If you're really worried, better to be safe then sorry and pull the bullets.

I fire 9mm berry's out of my sub 2000, 357 out of revolver and a Winchester, and full load 44's out of another revolver and another Winchester, never any issues with any of them. according to my load manual firing the 357's out of my Winchester can get them up to 1800fps, still no issues

No magnum rounds left loaded, shot 10 only. I won't get into the details of fault.

FAQ: Load Data for Berry's Preferred Plated Bullets

Currently published load data is limited to some calibers by Accurate, Western Powders and Hodgdon. We are working with these companies to get data published for all of our bullets.

We recommend using hard cast load data or start with mid-range jacketed data. Make sure data is below 1250fps unless you are using a Thick-Plated bullet that we list a higher max velocity for like the 9mm 124gr HBRN-TP that can be shot to 1500fps in open class guns like a .38 Super. Keep in mind that since our plated bullet has the same pressure curve as a hard cast bullet, the published cast data will be very close to what you will get with our plated bullets. If you use Jacketed data with our plated bullets you can get from 5% - 8% increase in velocity using that data.

Other than the data from Western and Accurate for the 9mm, .40S&W and Hodgdon .40S&W there is no printed data available.

NOTE: All of the hollow base bullets have a thicker plating and can be shot at 1500 fps the thinner plated bullets are designed for 1250. These plated bullets have lead cores softer than cast bullets, because the lead is soft and the jacket is thin they will expand and fill the bore diameter very easily. This expanding to bore diameter a can increase chamber pressure when driven over 1250 fps because of the soft lead core and thin plating which can distort the shape of the bullet and increase pressure. Meaning these bullets are not made for warp speed and must be kept at impulse power.

9mm/38 Super (.356) 124gr HBRN-TP 1000ct

Our Hollow Base allows the bullet to be longer and provides more contact area with the barrel and rifling which will stabilize the bullet and improve accuracy. The bullet profile is longer but the weight of the bullet remains the same and you can load these bullets using any published load data for a jacketed bullet as long as it is the same weight bullet.

The Thick Plate allows these bullets to handle velocities up to 1500 feet per second and is ideal for competitive shooters who are looking for increased accuracy and higher velocities needed for 9mm Major loads, .38 Super Comp/Open guns.

For the 9mm we recommend a COL of 1.160"

For the .38 Super we recommend a COL of 1.250"

Below the thin plated bullets are for light practice loads.

And the thicker plated bullets can be loaded to max velocities.

I also shoot Rainier plated bullets in 9mm, 40 S&W and 44 magnum.


Rainier Ballistics
Loading Data

We, at Rainier Ballistics, recommend using Jacketed bullet load data when loading our bullets. There is no need for adjustment when using Jacketed bullet load data. Our bullets are jacketed using an electroplating process and are softer than traditionally jacketed bullets; Be sur to use ONLY load data that is published in a reputable reloading manual.

***If you only have access to traditionally jacketed load data, we recommend a starting powder charge directly between the listed minimum and maximum load, and you may use published load data found in reputable reloading manuals.

A slight roll or taper crimp may be used with our bullets;

Overcrimping plated bullets may result in decreased accuracy, and fragmentation of copper plating.

Thanks for the kind words. I will not get into why these bullets were used.

Pressure signs were possible, (bullet squishing) as the heaviest loads were not as consistent fps wise, but brass and primers were fine. It will be interesting to see the difference with the Cam Pros.
