I'm zeroing my new CMP M1 for 100 yds at the local range using M2 or commercial non ferrous equivalent

Where is the 100 yd mark on the elevation drum? There is a tick mark below the 200 yd mark. Is that it?

What is the up-close prime ordinate range for a 100 yd, 200 yd or 300 yd range?

Is the elevation drum accurate? If I zero for 100 yds and dial to 300, will it get in the 10 ring?

I was going to post step by step instructions but this write up is better than what I would put down.

For simple target shooting you can do what is done for CMP shoots (the battle sight zero as descried in the previous link is not used for this).

Crank the sight all the way down. Now crank it up 6 clicks. Shoot at 100 yds and adjust up as need to get as close to the bullseye as you can. Most Garands will be on 100 yd zero in 6-8 clicks up from bottom.

When you shoot at 200 yrds go up 1-2 clicks and you should be close. I think 300 yds is another 3 clicks up. Write down type of ammo and the clicks you needed for each yardage on a piece of paper and store that in the oiler hole in the buttstock. Now anytime you or another person picks up the rifle they can refer to the Click data you wrote down and be pretty close on the first shot for those distances.

You really should record your zeroes for all ranges you plan to shoot at by counting the sight down to bottomed out once you are hitting centered at the range. That way when your sight comes loose you have something to go back to.
