in a bolt action, with a one in 7 twist, I've had no issues with the 40 grain Plastic tip bullets in the 223.
Whether from Sierra, Hornady or Nosler. And I use them on small pop bottle or water bottle sized sage rats, to distances of 250 yds or so. They hold up to 223 speeds out of any 1 in 7 twist barrel I've used them in...

and the twist doesn't negatively effect accuracy of the 40 grain Bullets.
