I have a Bo-Mar rear sight on my Dan Wesson 357 Supermag, and it has a 8" barrel on it. Can anyone tell me how much elevation one click would equal at 100 yds/meters? Thanks-
Bo-Mar click value?

Can't say for certain on a Bo-Mar, maybe 1/4moa. The DW rear sight on my SM is 1/2moa.
If you have a caliper and can figure out how to measure the height of the rear sight then you can calculate it.
Measure the height of the rear sight. Move it up 10 clicks and measure the height again.
Now take the two measurements and calculate the difference (the amount that the sight moved).
Now measure from the rear of the front sight to the front of the rear sight. That's your sight radius in inches.
Now take the amount the sight moved and multiply it times 3600 (that's 100 yards in inches).
Take that result and divide it by the sight radius in inches.
Divide that number by 10 and you'll have the amount (in inches) that moving the sight a single click will move the point of impact on a 100 yard target.
