News to me but I just read that any PH-5 fitted to an SMLE is 1/6ths off for distance. Supposedly the reason is they were calibrated for a Long Lee so there's a velocity difference & a sight radius difference that combined mean you need to use  6 clicks to get the effect of 5 on the range scale.
Any observations or thoughts?
Confused
Its an early 5A with the 1/2 MOA clicks BTW.

Ohh ok so it is one of the 1/2 moa units not the PH minutes sight, so that ideas out.

I have the exact same sight as you, now i want to check if its the same with mine.

It would also be for original ammo so probably irrelevant for your reloads anyway!
It's nice to be important, but it's more important to be nice!

Yes, I usually run 150 Gr at about 2550 FPS, so its more a curiosity than anything.
