Loading 77gr SMK for ..22-250?

Current availability (or lack there of) of all things guns has brought out a nasty habit in me to buy bullets and powder impulsively. At my last romp through the local gun store I had my mind on some .224 match grade bullets for my 1:9 model 12 .22-250. Long story short I ended up with a pack of 77gr match kings with the promise that I would like them. Of this I have no doubt but I can't find any load data for this bullet in .22-250. Any thoughts, does anyone load these in in their .22-250? Also let me say that I realize that 1:8 is the recommended twist and the Miller twist rate formula comes up with a stability value less than 1.4. Never the less I'm stuck with the bullets and intend to shoot them assuming I can safely load them.
 
alliant website and hornady 9th ed. manual both have loads for 75 and 80gr bullets in the 22-250.

As far as stabilization, you wont know till you try it. I shoot some bullets from my 14 twist that are very accurate despite being long for the twist rate.
