1-10' 22-250 Heavy Bullets

I have a Ruger American 22-250 w/1-10" twist. Would like to try some bullets in the 80gr weight class. I would like to hear from anyone with thoughts or experience on if they will stabilize or not.

Not enough twist to do much over maybe 68-73 grains depending on length.

Try AR Comp with a 69gr TMK. I had very good luck with a 1-8" Ruger American around 31-31.5gr
