I second the CFE223 it's given me my highest velocities in the Nosler and the 22-250
Dirty what loads were you using in your 18" vs. 20" comparison? The quick 18" barrel match I did on one load of 50's showed the 223 faster by 26 FPS hitting 3431 but I did have a bit more room available on the Nosler.

Greg, the 2 loads I used for comparison are 55 Hornady SP, BLC2 28.0, CCI#400, LC brass. 3370 FPS on warm days out of a 20" barrel. Brass is toast and primers are pierced on hot days. I haven't chrono'd the load in cool weather but the brass and primers are ok in winter. This is the fastest hottest load I have tried in 223.
The 18" Nosler load that gave me my fastest speed was H4198 26.5, CCI#450, Nosler 50BT, Hagar brass. 3598 FPS in the Stoner barrel. Primer pockets are loose. I think a couple 1/10's less powder would leave the brass in reusable shape. CFE-223 is close in speed and may beat the above load overall, but I can only ruin so much brass before I loose my motivation in beating the 223.
I have a 20" WOA barrel to replace the Stoner that will give me 2 equal length barrels to put head to head. Once I get it threaded I will start testing again.
