Next question, and I know the answer to this as well.
How does one crimp a LR case after it's loaded, given a bullet and case O.D. of .224" on both?
Tick, tick, tick, tick.....
IIRC, the primed, charged, and bullet loosely fitted case runs through a set of from rolls,.....simultaneously getting crimped, and the bullet OD formed in concentricity with the body. in some cases a Pattern is even rolled into the bullet's waist.
