Has anyone tested Staball Match in 223 with any ~77gr bullets? Hodgdon lists 24.0gr as max charge and velocity of 2750, but that’s with a 24” barrel. I want to see if this powder can at-least compete, or be close-ish to the typical mk262 powders.
 
According to my memory, johnnys reloading bench channel tried it in his mk262 series and it was bad

::::::EDIT::::::
JRB tested Staball 6.5 with bad results, not match.

It competes well with mk262 powders.

I settled on 25.2 with 77smk for mk262 clone. +-2750 from an 18" AR. This is a 5.56 pressure load & Hodgdon's 24gr max is at 223 pressures I believe. My gun just happens to shoot a little tighter with AA2520.
Also ran the 77smk's up to 3000fps from a 26" bolt gun with Staball Match.

I’m running 26 grains of stball match with a 80eld in a .223 AI and it was 2800 fps. That was just first charge I dropped. Going to go up 26.4 and see if I can get 2850.

22” bolt gun.
Damn. That’s quite a bit over hodgdon’s max. Any pressure signs? Are you loading them really long?

Here is another link with a lot of info. Load lengths given for bolt gun are up to 25.9gr and loaded long 2.430"+. I could have gone higher in the bolt gun but there is a 3000fps speed limit in Tac class & I hit that at 25.9 or less with the 77gr bullets. AR @2.253-2.294" & up to 25.4gr in small cap brass with soft primers.

All loads in the link below & previous link are 223 Wylde 8T barrels.
