BuffordBoone here has a 4 twist, 30 cal barrel and experiences bullet poofs (scientific term) at normal velocities. ...been meaning to ping him to weigh in on the pressure thread. ...now I can ask him about weighing in here as well.
I personally wondered how rifling plowing a new furrow constantly as I imagine is happening with a gain twist barrel leads to less pressure.
