Against the recommendations of about 1/2 the people I talked to, I did.
I just used to antique looking wood screws and mounted it direct to the wood. I can't recall if they were 1/2" or 5/8".
My tang sight is the one the other posts point out from Track of the wolf.
Problems I have had so far:
The tang sight really does not click at the perfect upright position, its leaning a little forward. I have found myself pulling it back with my thumb as I shoot to clear up the sight picture. I swapped around the base spring and it made it a little better, but not perfect. I have plans for how to fix that.
The sight hole was around .030", way to small for past 100 meters for my eyes.
first I opened it up to around .038" and it was a lot better past 100 meters, but was still dark past 400 meters. (I did have hits on the steel turkeys at 400 meters! )
This weekend I opened it up to .042 and its better, but I could not get onto the long range.
I might still open it a little more. I was reading about some expensive tang sights that talked about .048" for target and .05? for hunting or dark days. Don't forget to mark the inside of the hole black after you open it up or it will reflect light.
(If you double the size if the hole, you get 2X the amount of light. Note double means double area of hole, not diameter of hole!!!!!)
there is no marks for windage. You have to get it on target and put a scratch in it. To adjust elevation you have to loosen the eye cup which also locks the windage, in other words, the windage will change every time you adjust the sight.
At 400 meters with the lightest load of H4895 and 405 grain Lead, the sight was at the top of its adjustment range. I do have the "to high" globe site on the BC that came with it. changing that would help. Also a hotter load would help since I am doing around 1400fps if the books are correct.
I was told I should expect problems with the sight to move with weather/temp because of the way I mounted it on wood. Last weekend I sighted it for 100 meters. next weekend I will return to same 100 yards to see if it is still set.
the results at 100 meters:
27 grains of H4198 (yes I switched powder) with the 405 grain lead.
Using a shooting bag for a rest, barrel just ahead of fore arm wood sitting on bag. (I need to buy a better rest.)
Using the 28 front insert the black on the target is a little smaller then the 28 hole (you can see white around the black in the sight).
I had one 5 shot group with 4 holes in a 4 leaf clover and one shot to the side with 1/2" of paper between them (target in sun).
I shot a group of 20 in one string with target in shade, I had 10 through the 10 ring (2" across) with the other spread out to around 4" across group. the sun really helps with the small hole in the tang sight!
When I started this project, I figured if it did not work, I could fill the holes (and match color), or switch to these inserts that you mount in the wood and attach stuff with 4-40 screws.
so far I have no regrets. But proceed at your own risk after doing research.
For next weekend I loaded 50 rounds with different levels of H4198. If I can duplicate the results of what I saw last weekend I will go play with the cast bullet match guys in 2 weeks. Problem is they are all shooting $2000 guns with 20X scopes but I will still have fun, and that's what this is about.
edit: If you do use add one, take a pen and paper (and reading glasses) to document the settings for future use! You can spend a lot of ammo "walking the shots" up or down the target getting on sight when you have 3" of sight adjustment
