added the picture of the fire case

Never heard of that powder but will add it.

What did you get from these in the chrono testing?

I think that is the same powder used in the American Eagle cartridge that I did the other day.
It fits the profile for charge weight and velocity yield.

1157 FPS average.

I have some if anyone interested in a gel test,i can kick em out to you.

Intercooler, Were those JAG brass shot from your pistol?

Not bad, good chamber to keep them this small. 

I sent a few down to Raggedyman for gel. He has a slew to do when he can get to them!

Actually shot in three of my 10's! So all three are good which I always thought.

As for the Chronograph info:

Match 4.75" 1156, 1167, 1159, 1145, 1158. Average = 1157 FPS/ 535 LBS
Razorback 5" 1192, 1169. Average = 1180.5 FPS/ 557 LBS
1006 5" 1153 FPS/ 531 LBS

I didn't find the exact reference to the 1100 fps for the Skull Crushing HP Zombie Ammo but used the BitterRoot Valley Ammo which was on the Selway web site...   They may have been listed as 1150 fps originally.

I contacted the Company for the rating.

They are toward the slow end of the spectrum for my tastes.  Is the price super low?  In other words, why buy them over UW?  Or isn't there a real reason and we're simply reaping the benefits of another factory load pull down?

The original specs were removed for the Zombie Ammo at Selway, I think I recall them being listed at 1150 fps?
They were being sold as a bulk ammo in Zombie Ammo Box...

So they don't exist anymore?

They do exist still.  Selway armory in Missoula Montana is producing them or could just be selling them for BVAC down the bitteroot.  Both of them are close to me.  Selway started as online sales and now he just opened a retail store with the internest sales taxes recently implemented.

Does anyone have an inside contact to find out what the bullet they are using here? 

I plan on stopping by there sometime the weekend of June 8-9 I will ask then.  They may or may not tell me though.
