- Hi, I have a question that I would appreciate
- any help. I have a T/C 10" 44 magnum with
- a factory iron sight. Using an electronic
- caliper, I measured the rear sight's height
- at different clicks and this is what I got:
- - with the rear sight all the way down, it's
- 2.020 inches.
- - with 5 clicks up, 2.045"
- - with 10 clicks up, 2.063"
- - with 15 clicks up, 2.084"
- - with 20 clicks up, 2.108"
- - with 25 clicks up, 2.128"
- The click adjustments are not consistent. I am wondering
- is this a common problem wihth the factory iron sight?
- If it is, is there any iron sight that gives consistent
- clicks and it can fit the T/C without drilling and tapping?
- (Such as Williams ro Lyman?)
- Also, is there an accurate way of calculating the relation
- between MOA and sight click? (In other words, giving
- the sight radius, sight height (and adjustment per click),
- muzzle velocity, can we accurately calculate the
- MOA/click? I tried to calculate it using trigonometry
- but it seems the result is too far from being accurate
- after I tested in the range).
- I would appreciate any help/comments. Please either post
- your replies or email to me at minh@inst-sun1.jpl.nasa.gov
- and I'll post a summary.
- Thank you very much.
