Finding C.O.A.L. cartridge over all length for bullet jump.

In this video I show you an economical way to find the cartridge overall length, and then go from there to find the "jump" off the lands of the rifling.
As always consult bullet manufacturers for their recommended jump distance.
you want to do this process for each bullet weight and manufacturer as they will change between manufacturers and weight.

Thanks for rehashing this old school method. Its something reloaders should heed in lieu of taking chances or guesswork !
