Garand battle zero ?

I have a question about battle zero for the garand. I do not plan to do competition type shooting.....mine will just be for fun at the range so I decided to go with a battle zero. Now, following Duff's instruction in his book I should run the elevation up from the bottom roughly 10 clicks and then at 25 yards zero for a POI that is a 1 1/4 above POA. Now here is where I am not sure of the next step.
I believe the next step is to loosen the elevation screw and adjust the knob before re tightening but just exactly which line on the drum should I align the range? the 100 yd or 200 yd or different.??? By the way, just so happens that at ten clicks up it aligns perfectly with the 100 yd mark already. Thanks in advance.

Goal: When you shoot at a known range (say 100 yds or 200 yds) the drum reads the range when you hit where you want. The use of distance above 25 yd zero is just to get you near. If necessary change drum until this works. Then you can dial in any known range. Note: if you are in a "competition" you will probably have to write down click adjustments to get you "right on" at various ranges. This is why NM rifles have smaller click adjustments, but that is another story.

With the sight reading right on the rifle range, there is a longer line with no numbers which is the "battle sight " distance. I believe this is ~300 yds. This will get you "close enough" for most quick shooting in a battle.

In Basic Training at Ft. Dix in 1960 we were taught to perch the bull on the front sight blade like a pumpkin on a fencepost. The right zero was a 3-shot group on the edge of the bull at 6:00 o'clock. That sounds to me like the point of aim was the same as the point of impact at 25 yards.

When I went through boot camp at Parris Island in the mid 1950's we were instructed that "battle sights" were set at 13 clicks elevation and zero windage.

Thanks for the suggestions.

13 clicks was only a starting point, all rifles are different. Average elevation is 9-11 clicks and we started from there. One guy needed 28 clicks to get a zero, others went the other way and ended up at 2 or 3.

My Winchester is 18 clicks up.

I have a question for you guys along the lines of this thread topic. I'm just a casual shooter, doing my best to accurize my Garands as I go along. I picked up a CMP special grade Garand a while back from a friend of a friend; I haven't shot it yet. Here's the thing: The front sight is adjusted almost all the way to the right.

Can I re-center the front sight and somehow adjust the rear sights so I can line it up centered? How would I go about making the rear sight adjustments? Thanks again fellas.

The front sight is supposed to be centered. The rear ideally should be centered too for shooting but some are a bit off. If it's off by much then your barrel is out of index, that is not top dead center. This happened occasionally and can be corrected. The rear sight can of course be adjusted left and right for minor moves with the windage knob(on the right).
