Greetings @Micky Duck,
I now check the crush length for each new batch of projectiles and adjust the overall length of the round to give 1mm clearance. I started doing this after noticing that the position and shape on later batches of Hornady projectiles were further forward than older ones. Recently setting up to load the 60 grain VMax projectiles in one of my .223 rifles my measured crush length was about 1mm shorter than the cartridge overall length given in the Hodgdons data for the same projectile.
