Here is a pick of a 22-250 case with the neck sized to 6mm then down to 224. I just
ran it through the 243 die, then set the headspace to a tight bolt close on the neck
with your .224 die
I can't recall the exact recipe but I tried quite a few loads for my 6mm and when I tried VVN140 and Sierra 85 grain hollow point boat tail I started getting 5 shot groups inside a dime at 100 yds.
Give the 88gr Berger FB High BC Varmint a try on the yotes. depending on the twist the 87 or 95 gr VLD's are killer on deer sized game. I use these in my 6mm-06....Deadly
