Parker Hale aperture sight threads 7/32-36 TPI

[akaroa1]

Well I did track down a full set of 3 taps for this job on loan.



They were only a short drive away and the gift of some fresh venison.
I know where they are for next time I need them.

Nicely converted the tiny edged rimfire sight staff to take the Parker Hale eye cups.
Played around to find an aperture size that gives a good sight picture with the globe front sight



Now I can continue with the load development and have a better chance of grouping with this 140+ year old rifle which has a very good bore
