Sierra .224 55gr Blitsking ,anyone ever shoot this bullet out of a 22/250 with 12" twist ? At 3100 FT elevation the Berger Twist rate calculator says its stability is marginal ????

I shoot them in my Cooper 22-250 1-14 twist at 2800 feet. I've shot squirrels consistently out to 430 yards and have never had a problem.
