The only problem i had with my quick twist was the fact i could not shoot the 55 grain or lighter bullets because like Seafire said they turn into a grey mist a few feet in front of the muzzle.
I've got a great buddy with a 22-243 Middlestead that shot nothing but Nosler 55 grain BTs through its 8 twist. Shot knot holes and never lost a bullet. It was wicked on antelope. The BT's have a thick base and sorta thick jacket for a varmint Bullet.
