  *Primer pellet turned to dust and mixed into the powder turning it yellow green color...had to beat the hell out of this one to remove the bullet.
**Sealant glued the bullets inside the case making it difficult to pull (over 50 strikes with the kinetic puller)

















Added the second powder charge picture, I cut the casing with a dremel so the bullet could be removed with out the primer pellet breaking up and discoloring the powder.

Power Pistol or BE-86 possibly?

[The_Shadow]

I tried to clean the powder with dry paper towels rubbing it to remove the primer mixture.  Powders are somewhat porous so it still had a fair amount stuck to it.
Here is a picture of the pulled powder after I tried to clean it next to Power Pistol from 2008

[DAVIDF]

Yes, it would seem that Speer would use a flash suppressed propellant with any of their Gold Dot loads. 7.6gr of BE-86 would be a max load for a 190gr JHP per Alliant's online load data.

[The_Shadow]

I was thinking the same thing that it would be BE-86 and it very well could be.   With the discolorations of the powder from the priming pellet breaking loose it makes things difficult. 
I'm going to try an pull the other one, but I will heat the casing up, to see if the sealant will soften to allow the bullet to pull easier.  The first one had plenty of sealant.
I have never had to hit but a few cartridges that hard (usually ones with very light projectiles) or as many times as I did this one.  Hoping the second one will pull easy and show better.

Just taking some time to think of what other tools I might have to pull it with.  It might be better to take a dremel tool and score the casing and cut a groove or two so the bullet can come out easy.

I'm glad to see that I'm not the only person who had trouble getting one of these disassembled. 

On a positive side they should be environmentally stable for carry afield as EDC ammo and there is little chance of bullet setback with repeated chambering.

Now patiently waiting for Speer to offer the 200gr Gold Dot as a component. 

[spencerhut]

You should be using a press mounted puller, much less work. RCBS and Hornady both make good ones.

[The_Shadow]

I'd be willing to bet that a press mounted collet puller would have a difficult time and might damage the bullets beyond reuse. 
I have pulled many thousands of cartridges down and have only had maybe 4 or 5 that had issue.
More to follow...

[blaster]

awhile ago I bought some .40 Gold Dot pulled bullets from American Reloading. those bullets had some of the black sealant you are talking about. I wonder what they use to pull massive quantities of bullets without damaging them?

[The_Shadow]

They use a collet type puller but you will see a crimped line in the jacket where the collet grabs the bullet on each side and most of the way around.

[The_Shadow]

OK, I added the second powder charge picture.
I cut the casing with a dremel so the bullet could be removed with out the primer pellet breaking up and discoloring the powder.
To me it looks like Power Pistol the charge was 7.0 grains even.

[Intercooler]

I thought it was 7.6? Was that due to primer material being in the first one?

[The_Shadow]

More than likely the primer mixture accounts for 3 grains give or take...

Took some comparison pictures today of the two different Speer Gold Dot bullets
Here is the close up of the two 200 grain Gold Dots, notice the amount of black sealant on the back right, it was glued inside the casing tight...
Bullet on the left is #53883 Bullet on the right is #54000







Intercooler tested these two bullets as loaded Feb 28th 2018
This was the reloaded 200 grain Gold Dots, one was the new style #54000 and the other #53866 the 40S&W contract pulled with known powder as shown.

200gr Gold Dot #54000/#53883 7.4gr's Power Pistol
EAA Limited Pro 4.75" 1013, 1071 Average = 1042 FPS/ 482 LBS

200gr Gold Dot #54000/#53883 7.4gr's BE-86
EAA Limited Pro 4.75" 1096, 1099 Average = 1097.5 FPS/ 535 LBS

200gr Gold Dot 7.4gr's *(don't know if it was PP or BE-86)  *This was the original powder from the pull down used with an old style #53883
EAA Limited Pro 4.75" 1106 FPS/ 543 LBS

Remember that the Factory ammo the bullets are also sealed in the casings...it is what made it so difficult to pull and broke the priming pellet loose in the initial pulls

Thanks!

Now if someone would just kill some Jello...
