Seafire,
That was probably me that posted the scan of that data. They published load data that included Blue Dot with jacketed projectiles circa the mid 80s (from memory) for the 221Fireball and a few others in the Australian Shooters Journal.
I ran that load above by the way through QL which estimates a much slower speed (about 3100fps), but what is significant is that muzzle pressure is reduced by about a third over a 'normal' 223Rem load at 3300fps. That in itself is a worthwhile gain when there's lots of shooting to be done and your on smaller farm lots.
Cheers...
Con
