Al, I find myself wondering about a couple of your statements in your two post above. Your comment on case annealing has me wondering what VOODOO there is with case annealing and being able to chamber a round.
Also what in the world does Ogive shape have to do with twist rate? Bullet weight has nothing do with twist rate, it is the “Length” of the bullet that determine’s twist rate.
Not saying you are wrong but I sure would like to hear your thoughts on these two subjects.
