New Bullet Comparator

[mac86951]

I happen to work at a company that has an attached machine shop, and in my reloading I've come up with the following idea.

I'm not worried about sharing the idea, though if people are interested we'll pursue the business. I trust enough people here to share the idea and see if anyone is interested?

In my searching, competing, and reloading experience, a variable that remains popping up is bullet sorting. It seems to me that there are three methods to solve this issue:

#1: Buy better bullets. (longer waiting list)

#2: Use comparators that are available, this means either the Hornady style, or the Sinclair style, both use your calipers, one really needs a dedicated caliper.

The issues with what I've seen are: The Hornady unit requires dedicated calipers, and the Sinclair style really measures bearing length to base of the boat-tail, not really the bearing length.

I figure why not make a precision mic style bullet comparator? You can then tare the weight of your measurement tool and get sort by bearing length and weight if so inclined.

I've found this need for 77gr Sierra .224 bullets, and certainly the 142gr 6.5mm Sierra.

Any thoughts or ideas on that or is this something that few bother with?

Exactly, one like that that won't need the dial indicator and granite stand.
