Hi all,
First of all, Mods feel free to move me if this is the wrong forum. I just figured that these guys would probably have the most technical knowledge.
So sometimes I get bit by a curiosity bug and it causes me to research and research and dive deeper and deeper until i'm satisfied (thats what she said). The most recent case has developed as a result of me trying to pick what ammo to buy/test for my new platform (SR-15 with TA31 ACOG). I know its not a tack driving setup but why not pick the closest/best match possible, right? Which leads me to my problem:
Trijicon states that the BDC on the TA31 is calibrated using a 62 grain bullet @ 3050 FPS. I have not been able to find any other information. As you can see that leaves it kind of vague. Whats the BC? Fired at what elevation, temp, humidity, etc. Again, I know this is by NO MEANS a precision/long range optic. But again - why not utilize it as best as possible (without forcing myself to use 1 kind of ball ammo).
Now the question:
Does anyone know A) what bullet they used to calibrate this OR even better B) the drop distance of each BDC hash mark. Because thats all that really matters. If I could know that the "5" hash mark = 65" drop @ 500 yards thats all i'd need.
Anyways, I know its a long shot but figured id ask anyways.
Thanks!
