number of clicks
just a question to get some comments. you have your M1. you go to the range. using military ball ammo. wind not an issue. roughly how many clicks of elevation to get you in the 10 ring at 100, 200, 300 and 500 yards?
For me, none. Mine is sighted in at 200 yards, I just use Kentucky windage from there. Then again, there are no ranges over 300 yards in my area.
An easy way to figure out the clicks is to use the 10, 20, 30, 40 50 yard shots, and their placement to get yourself close. If a rifle is sighted in at 250 yards, it will hit pretty much in the same spot at 25 yards. Start at 10 yards, shoot a 5 shot group. Record the size of the group, then do the same at 20 yards, etc. Record the number of clicks at each distance after the first one at sight in, and try those adjustments when shooting further out at the "comperable" distances.
Best I can come up with. I was taught by an ex-Marine who used to pop the plugs out of his target at 500 yards during qualification, so what do I know? ;)
On a lock-bar sight all you have to do is:
1. Set up a target at 100yd
2. Come up 10-12 clicks and shoot
3. Adjust until group is centered
4. Loosen screw on Elevation Drum Cap
5. Turn the Cap by itself to align the line under the "2" (not the one right at "2") with the index line on the Receiver
6. Tighten the Cap screw
The "Battle Range" triangle is fixed at 300 ("3" on the drum). You don't need to do anything for that. Aim Center of Mass and you'll hit somewhere on a man-sized target from 0-500yd.
All those little numbers are only good for "minute of enemy" with standard service ammunition (ie, M1 or M2 Ball, M2AP). When your platoon or squad leader says "Target, 400, right front, enemy infantry" you come off your "Battle Range" put the "4" on the index and engage.
