Looking for some powder suggestions, 40 SW and 223 ar's

My chrony could be failing, or perhaps I'm exaggerating. It's all cool.

Vell vell Nicolai..... undt I t'ought you ver DEAD!!

Schtill wit' the hyperbole eh? The unsupportable claims??

"Tesla" is perhaps a Freudian schlip???

LOL

no...go look at my numbers and thiers..they are using a shorter oal..with a hp......i used a rn...so if you measure the two to the base i'm guessing usable case vol is about the same...
how long is thier test bbl ???
thier 1.12 oal with a 180 gd and 7.2 gr is 105% case capacity...so a compressed load....and they are only claiming 1000 fps....
what pressure do they show for that load...i'm guessing very close to max.....
i doubt you can get more powder in the case...
there aint no magic in this game....
again not with in design pressure limits.

40 S&W 155 gr Speer GDHP Speer 1.12 4 CCI 500 Power Pistol 9 1,213 -
40 S&W 165 gr Speer GDHP Speer 1.12 4 CCI 500 Power Pistol 7.8 1,081 -
40 S&W 180 gr Speer GDHP Speer 1.12 4 CCI 500 Power Pistol 7.2 1,013 -

So you don't think the 1100fps "claim" is achievable, maybe because of my longer barrel, maybe my charge was more than 7.2?
 
the numbers do not add up ..
i would suggest you call thier tech center and ask more info..
what is the case volume of the cases they are using, is it a compressed load...

i shoot a 180 golden saber in 10mm at 1225-1250..across a chronograph from a 5" bbl
more case capacity, longer bbl higher operating pressure.....( than thier 4" bbl)

you are expecting another 83 fps from 1.5" of bbl...

nice to take things out of context,,,,,..
they ues a 5.5" bbl and they are NOT using power pistol...WHICH IS WHERE WE STARTED...
