Parker Trojan Choke question.

Absolutely pattern it not only to check the pattern but more importantly to check for point of impact. Good luck with your Trojan.

Thanks Daryl,

I will have to double-check it when I return home. I wouldn't be surprised if I wrote it down with the barrels off the gun, upside down, and flipped R and L with the choke diameter.



Is there a simple tool for measuring bore diameter in the Trojan steel 12g barrel? Or is it a known measurement?

I prefer not to spend a bunch of money on a tool I'll use 4 times in my life.

Thanks again.

What you will need is called a bore micrometer Jason and if you search this forum or the net you might find one for a reasonable price. If not find a local gunshop or gunsmith who might have one that could measure it for you. If you post where you live maybe one of our members could help you out.

If you get into these old doubles you will find a use for one.
