For those that have seen or use the Desert Eagle pistol in your video game play or even airsoft wars. Most of you know it shoots a 50 caliber bullet but have most likely never held or even seen the gun and its ammo. The first video below is shot with a high speed camera with a relatively new shooter attempting to shoot a bowling pin with the 325 grain projectile. Note the recoil or flip of the gun and the huge fireball. Keep in mind this video was shot in daylight. The flash from the muzzle is blinding in the dark.
Want to see more details and a closer look at the Desert Eagle 50 AE? This video below is a review of the gun. Be sure and watch to the end for some footage of other new shooters taking shots with it and a Freedom Arms revolver chambered in the same 50AE cartridge. That revolver is not for a new shooter. The recoil is unbearable.
In the videos below I will show you the process of reloading this monster 50AE (50 Action Express) round. Even though the video(s) is caliber specific, the information on the process is pretty much universal for reloading other calibers. If you are curious about reloading or looking for information on the subject, these two videos are for you.

RCBS Chargemaster 1500 Defect & DIY Repair
After many years of dealing with my RCBS Chargemaster 1500 combo that appears to have an issue with responsiveness in reference to the keypads, I decided to make the following video and send it to RCBS and see if they had a solution for the issue. Be sure to see what really fixed the scale near the end of this post.
Here is RCBS's response via email:
SOMETIMES THIS IS DUE TO THE CONNECTION ON BOTH UNITS. DISASSSEMBLY BOTH UNIT AND APPLY ELECTRICAL GEL ON BOTH CONNECTION PORT. REASSEMBLY AND PRESS FIRM ON BOTH UNITS WHEN ATTACHING THIS WILL GIVE A GOOD CONNECTION WHEN COMMUNICATING. USE A LAUNDRY STATIC REMOVER SHEET TO REMOVE ANY STATIC ON THE BLACK PLATEN. RECALIBRATE YOUR SCALE AND LET US KNOW.
So I gave the reccomendation a try. Here are the results:
In short the procedure RCBS recommended did not fix the issue. Below is the email exchange with the RCBS tech. I realize that my particular unit is clearly out of warranty and I do not have any illusions that RCBS would repair of fix my unit for free. However I thought it odd that RCBS would not "middle" any repair work since they have the most knowledge of the product and connections to the manufacturer. But instead they pointed me in the direction of a "calibration" equipment company when calibration is clearly not the issue.
If anyone knows how to fix the problem seen in the video, please let me know.
Nic:
I finally got to try out the suggestion and the problem still exists. Can you assign an RMA number so I can send this scale and powder dispenser in for repair? I have the original box to ship it in.
RCBS:
HOW LONG HAVE YOU HAD THIS UNIT?
Nic:
it's been years. 5 maybe???
RCBS:
I AM SORRY WE DO NOT REPAIR THESE CHARGEMASTER UNIT. WE PURCHASE THESE CHARGEMASTER 1500 COMBO SCALE AND OUR VENDOR DOES NOT ALLOW US TO REPAIR. PLEASE TRY TO CONTACT MICRO PRECISION CALIBRATION INC 1-530-268-1860 AND SEE IF THEY CAN REPAIR THE UNIT.
Nic:
Hold on. You sell your branded RCBS unit, but do not repair or replace? But rather direct issues back to the OEM/ODM?
What is the website and address of the OEM/ODM?
RCBS:
THESE UNITS ARE PURCHASE OVER SEAS BY EXCELL.
Nic:
I did contact RCBS right? Not some other vendor? I find it odd that the company that brands and sells its product with it's company name on the product would point to the vender for issues and not the company that sells and markets their own products.
Seems kinda like buying a Ford and having an issue with the Ford and then Ford referring the customer to the plant that assembled the Ford.
Here's the site associated with that phone number

I do not think calibration is the issue. I will dispose of the unit and go with another brand. Thanks for your time.
RCBS:
I AM SORRY TO LOSE ANOTHER CUSTOMER BUT THIS IS JUST WHAT THE POLICY ON THESE CHARGEMASTER UNITS. THERE IS 1 YR WARRANTY FROM FACTORY FROM THE DATE OF PURCHASE. MICRO PRECISION CALIBRATION IS JUST ONE OF ANOTHER COMPANY THAT I KNOW THAT MIGHT HELP. THIS MICRO PRECISION CALIBRATION DOES NOT ASSOCAITE WITH US RCBS.
Nic:
Yeah, I paid the extra for RCBS when shopping for a scale because there are plenty of other brands cheaper for the same features. However, I've had good luck with RCBS until now. But it looks like the extra expense was not worth the frustration in this case. For what it is worth, I've had this issue for years with this scale. I finally got tired of messing with it.
THE FIX
After taking a few says to think on it, I borrowed another Chargemaster 1500 from a friend and swapped the parts of the unit and was able to isolate the defective part. Turns out my powder dispenser unit was causing the problem. I voided the warranty (already out of date) and took it apart with 4 simple screws. Take care not to damage the ribbon cable inside when you unplug it from the small PCB inside the dispenser.
After inspecting the little PCB I found that the connector that connects the dispenser to the scale had "cold solder joints". Cold solder joints are solder joints that did not cool or flow properly when the soldering process took place at the factory. This is a manufacturing defect and should have been caught by the QA process at the time of manufacture.
This is a relatively simple fix assuming you have a soldering iron. Just reflow the solder joints on the BERG connector so that the frosty looking solder joint is nice and shinny. Adding solder to the joint and using flux will make it easier to reflow. The video below shows a sample of the soldering process and speaks more in depth of the error.
