Something I've always wondered is why there is no locking ring on the depth plug on the RCBS seating die, off the 3-die rifle set. I don't crimp with this die, using instead the Lee Factory Crimp die to roll crimp my 45-70. After going through trying the set the bullet properly within tight tolerances to a proper depth, I don't get why RCBS doesn't just put a lock ring to set the plug in place. As it is, I plan to just use a line of white out to make sure the plug and the die body are properly lined up (along with measured COAL).
But I don't get the lack of a locking mechanism. Am I missing something?
