New Lyman sight

[oncewas]

Hello everyone
I just got a new Lyman 57GPR sight and need to sight it in. So I was wondering at what range most people sight one of these in at. I normally sight in at 25yards for both BP and unmentionables and then re-sight in at 50yards but wasn't sure that is what I should be doing with this sight. Thanks for any help.

Would line it up with the existing sights (if still on the barrel) and get on paper at 25 yards. I typically found that to zero them on TCs, shimming the base up and or using a lower front sight was required so the sight is not already adjusted high from the base at closer ranges.

Okay so you did use the enclosed shim block? and did you use the target or hunting ring? The target is very small.

I use washers to get the height that works with my front sight, then either make a shim to that height, or you could just leave washers (I use stainless ones). Every setup can be unique. Use different site rings for different situations. In a low light scenario may remove rings and use threaded hole in the sight as a ghost ring. I use a Lyman globe (AHB I believe) and Lee Shavers inserts for front sight.
