crimping rifle bullets

I use Lee and crimp all my rifle reloads, 5.56, 7.62x39, 7.62x51, 30-30, 270 Win, 30-06, and 7mm Rem Mag, both bullets with and without cannelures. Discovered decades ago that a little crimp helps accuracy. Also discovered that too much crimp can hurt accuracy. To me crimping is a process one has to acquire the feel for. Sometimes I'll even adjust the Lee crimp die a little for one bullet out of a batch I'm reloading, because the pressure required to complete the crimp is excessive or too light. Crimping rifle bullets for use in a non-tube mag is a personal preference thing, kinda like shaving...some shave in direction with their whiskers, others shave against them...
