Posting here instead of Ramslamer's "Staball Match" thread to keep the data together, and to not open another thread.
My results with Winchester Staball Match, new Starline 6.5G brass, CCI 450 primer, Hornady 123gr SST loaded to 2.255. 3 round averages. This is informational only and not recommended load data. And no cool pics like Zeneffect...

Brass and primers look very good to this point. It appears my velocities are in line with what Zeneffect saw from his 22" tube. I would agree with Zeneffect that there is room for more pressure, but I am pretty much out of room for powder at this point. As noted in the 30.5gr column I bumped my coal a bit as powder level was very near the bottom of the neck and I am sure there is some powder compression happening. I could go a fair bit longer on OAL as throats on both guns will allow but not sure it will get me a whole lot more. Zeneffect, were your 30.6 and 30.9 loads compressed? Accuracy was decent and the 30.5 load turned in a 1 moa group for the mini and 3/4 moa for the AR in a decent cross breeze. Also, every round in the AR gave full lock of the bolt and 4-5 o'clock ejection with the Superlative Arms agb at full open no bleed off, carbine buffer and Geissle 42 spring. I was not always getting that with CFE223, even up into the 31.0-31.6 grain range.
