I have a 26" Rem 700 VLS .223 that really likes 50-grain Ballistic Tips and 26.0 TAC, although admittedly it shoots H335 just as well.
As for .22-250, the last 5 listed are all good. Personal favorites with a 55-grain bullet are 34.0 H4895, 36.0 to 37.0 of RE15, and 39.5 of H380. I also like Ramshot's Big Game. My rifle shoots its best groups about a grain or so below maximum.
