I was thinking the OP needs to invest in a 22-250.
I know this sounds dumb as its contrary what is out there in the shooting world...
however I have found it to be more user friendly in the 223 for accuracy than in the 22.250..
if nothing else, you can end up loading it hot in the 22.250 pressure wise.. but not in the 223.
in fact in the 223. if you look at load data for it with H 380... you'll notice it gives pretty darn good velocity, but at 29 grains with a heavy bullet is pressure is only in the low 40K range and great accuracy.. in the 22.250, its a little picky on accuracy, depending upon your charge and bullet weight.
its hard to blow yourself up when used in a 223... it can be done in a 22.250 if you get a little overzealous on the powder scale or on a real hot day.
