...a 50 grain Speer TNT over H322 has always worked for me, enough powder to get @ 3200 fps and rock on.
Like your way of thinkin Hank.....
I don't shoot a 222, but you certainly can create the same thing by loading a 223 using 222 load data....
I do a fair amount of that, and also down to 221 Velocities using its load data...
I burn a lot of H 322 annually and usually buy 2 or 3 of the thousand round boxes of 50 grain TNT's each year...
That little pill performs real well, and even better with H 322....
