Daniel and Tim, thank you both for your responses.
I have tried at least two of the calculators and obtained a total front sight height of around .875". This is measuring with a ruler, then converting to a digital measurement. I don't have access to a caliper or micrometer. As I recall, a third, I don't remember which method I used, I came up with a total height of around .813". Both of these numbers appear to be a very high total height for this rifle in appearance, using a cut out to simulate the total ramp and sight height. I also called a sight company for a recommendation that I understood was a best guess (that I would not hold them to) based on a work up of another rifle that had been done there using 30-30 ammo of unknown bullet weight. This guesstimate was .656 total height. There is around a .225" difference between my estimate and the other one. This seems to me to be a significant difference. I understand shooting the rifle is the best thing but it is 65 miles to the nearest range for me. I am not looking for perfection on the front sight but correct enough to allow for appropriate adjusting by the rear sight when I go to the range. No vender is close that has firesights of the appropriate height without ordering so I would be ordering myself. Right now I am thinking about going with a 3/8" Williams Shorty Ramp with a .450" Ht, .250" W Firesight insert. Would there be a significant difference in adjustibility or usability in going with a Williams .406" Firesight insert instead of the .450" insert in your opinions to make the front a little shorter to prevent snagging, bending etc? Any additional thoughts or opinions?
Thank you again for your interest
