  I Chronographed the two put back together Underwood rounds today.

Underwood 115gr +P+ Gold Dot EAA Limited 4.75" 1493 FPS/ 569 LBS
Underwood 124gr +P+ Nosler Eaa Limited 4.75" 1397 FPS/ 537 LBS

  and also Shadow's 121gr Zero +P+ Auto Comp 6.4gr's (Underwood 124gr load)... wait for it.....








EAA Limited 4.75" 1376 FPS/ 521 LBS

[The_Shadow]

They were smokin' along!    I think I saw 1447 fps in the first test I did with Kevin's load from the Ruger P-85 back then.
What was the previous data from the one's previously tested?   
Did you get the brass for those?  If yes how did they look?   

[Intercooler]

  I did, however they are now all mixed together. I don't recall anything crazy and it looks like the mystery is solved.

[The_Shadow]

I want to say that the number were very close to what you got in you original test shots!  Here they are...
Great results as usual!

About a 65 FPS increase over the 4.75" Limited barrel. I guess if you have a 4.5" -4.75" barrel you are getting about all you can out of 9mm rounds.

That was a great experiment, for never having seen AutoComp powder, studying and profiling it's performance, then obtaining pictures to compare, then obtaining an actual sample to verify!  Its why I like doing this stuff! 
The 121 grain Zero bullet is a true 0.3560" diameter, that would account for some extra drag, but should be very accurate!

Now I need to get that G-23 to my brother and turn that money into a 9mm pistol for me!  BTW, I was looking for a 9mm before the G-23 was dropped in my lap!

[Intercooler]

   I want a CZ. In particular a Shadow and since you borrow some of that... I vote for you getting a CZ Shadow 9mm.

[The_Shadow]

Yes I'll have to consider that one, hoping for a good spring and summer for grass cutting to make a few dineros!  Either that are hit the lottery!   

[Intercooler]

  If you do really good go for a Hi-Power maybe. My Limited 9mm shoots the cartridge like a dream!
