M1903 sights

Hello all,

Hope an off-topic - i.e., non-M14/M1A post - won't be a problem, as I have not yet found a forum devoted to old mil-surplus bolt-actions like my Springfield M1903A1.

I enjoy my M1A and M-1 a great deal, but occasionally take a break from them to uncase an old friend, my M1903. My previous Springfield-pattern was a Remington M1903A3, which I have since sold. I traded up to a M1903A1 specifically for the M1905 sights, which are - to my eyes, anyway - pretty advanced technology for iron sights, circa 1905.

I'd like to develop a highly-accurate handload for the rifle which tracks closely with the elevation graduations on the ladder sight. I am having trouble tracking down data on the rear sight ladder, specifically the value of the elevation yardage markings on the sight in minutes-of-angle or inches. It would help a great deal in designing this load if I knew more about the sight itself, and wondering if there are any M1903 aficionados on the forum.

Also, I am wondering which of the various 30-06 service loads over the years tracks most-closely with the elevation marks on the sight - i.e., M1906 ball, M1 ball, M2 ball, various National Match loads, etc. Any insights here appreciated.

The ladder sights, being a form of bullet drop compensator, aren't going to be "on" at all times and places or under all conditions.... I get that.... I just want to design a good general purpose target load that gets as close as possible.

Since I'll probably want to use whatever load I develop in my M1 Garand as well, I'll be restricting bullet weight to 147-178 grains, and use powders suitable for the M1 as well as for the M1903.

Thanks for any advice, input, etc. - much appreciated!

You can find all the data regarding your ladder sight on Google. I also have an '03 and found the article very helpful. They are a grand old rifle. The ladder sight is probably the worst battle sight ever for can be damaged easily and takes fine eye to use that notch.
I opened up the aperture a bit and now with brand new lens in my right eye(surgery) may even be able to use the notch.

I would load as stevriot pointed out with a 168 grain SMK using IMR 4064 or IMR 4895 powder; get a chronograph to define what powder charge increment performs best. Stick to whatever combination of primer and powder type/charge weight shoots best and is most consistent out of that rifle.

I would then calibrate the sights. As you pointed out in the OP, the rear sight design of the M1905 rear sight is well thought out. With regard to your question in the OP, yardage elevation can be set to correspond to the exact number on the rear sight ladder. The battle sight, however, is a general 547 yards with an M2 ball type load. Each windage hash mark moves the shot group 4.4" at 100 yards.

I have found that the rear sight can be very accurate to the yardage you set the rear sight ladder to. How is this accomplished? I have done it by setting the rear sight ladder aperture, which one you use is up to you and your eyes, at a specific yardage; lets say you target is known to be at 200 yards distance. Raise the aperture to the 200 yard hash mark on the rear sight ladder and tighten the elevation knob. Assuming you already have centered the windage, fire five shots to establish a group. If the rifle groups low, very carefully file down the front sight blade. Continue shooting and lightly filing until the shot group is in the center of the black, or the center of whatever the target is you're using. Once this is done, the sights are calibrated. If the rifle should instead shoot high, install a known new front sight blade. Check the action screws of the stock to make sure the stock and action are tight.

From my experience using the above method, I have found both M2 ball and M72 match (or a tailored load of 175 grain SMK) will not be noticeably different or require change to the rear sight setting.

An M1903 iron sights were set to match the Cartridge, Caliber .30, Ball, M1906.

Since, M1906 and M2 are ballistically the same, M2 works. They never got around to making a dedicated sight for Cartridge, Caliber .30, Ball, M1.

The BC for M2 ball is around .410, with a Vm of 2800 fps. You can use a ballistic calculator to match you load to that.

Thanks from Rich D

Here is a link to a document I wrote regarding the use of the M1905 sights.
