Are you recommending a standard throat length with sufficient freebore to accomodate VLDs seated a little further out?
p.s. to your point about taking a chance on rechambering, I imagine Shawn Carlock and Kirby Allen just consider barrels expendable in their R&D with throat designs for the +P, etc...
Sorry , I thought he was talking about shortening the neck to allow the VLDs to be seated close
to the lands there fore making it to short for standard ojive bullets unless seated deep.
The standard throat is .071 before the start of the leed. the neck is .272 +.000 - .020 long
The standard leed angle is 3 degrees and with the secant ojive of the VLD it would have to be
seated long to get close to the lands.
But if this is done it will make it to close for the standard ojive bullets and pressures will go up
(Or powder loads will be reduced) slowing velocities.
