Brownells punch sets

[TheWaker43]

I was looking at the roll pin punch set(230-112-105) and the roll pin holder set(080-685-000). They are both sets of five, each containing 1/16", 5/64", 3/32", 1/8" punches (#1-#4). However the largest size differs. The roll pin set has a #6 or 3/16". The holder set has a 3.5mm. Anyone know the reason for this and what large sizes might be used for?

I've got the same set and wondered myself, sorry no help from me.

I have those same punches as well and I also can't find a use for the largest of the punches.

I assume they must be commonly used in gunsmithing or they would not have been chosen. Anyway, I asked on the Brownell's Q&A, if I hear back I will post here if anyone is interested.
