IIRC that the encapsulating machine dies @~.68 caliber already existed when they first came up with the idea of a marking gun for cattle/trees/etc... No need to make special tooling for a new [limited volume] product. I remember bath oil beads that fit into my paintguns. So the guns were designed around the .68 caliber size not the other way around.
