The battle sight is actually calibrated at 547 yards. This has to do to the change from the .03-03 cartridge to the .30-06 cartridge. The sight ladder was changed, but the battle sight was not re-calibrated. In WWI they found their calibrations for the cartridge above 1200 yards was also short so they had to change the sights again, but still kept the 547 yard battle sight for whatever reason. During WWI every soldier had to pass marksmanship training with that battle sight by hitting targets from 100 to 600 yards.

I believe I have read that 547 yard dimension before. With all things being held constant if I shoot at 500 yards my group should be a bit to the left having the projectiles not travelling far enough for the full spindrift correction to be evident. I plan to test this at the range the next time I go out. Thanks for sharing that!

Do the math. 547 yards equals 500 meters. Even back in 1905, there was no avoiding the metric system.

Maybe copied the sights from Spanish and European Mausers.

@yourarsenaladvisor 1000 meters was a common battle sight range. Aim for the belt buckle with a 500 meter setting and, theoretically, hit troops advancing in the open at anywhere from 0 to 1000 meters somewhere on the body. Feet. Chest. Head. Didn't matter where. They were still casualties. My guess is that they snuck in the 500 meter battle sight, and called it 547 yards in the manual for domestic consumption.

When the ladder is in the lowered position, that sight you refer to is the battle sight. And is graduated to 547 yards as others have stated. The ladder in the raised position has three sights if I recall , now over the times this rifle was in service, they did issue different types of ladders , the WW1 period ladder at the top of the ladder , was a u notch, volley sight The other sights on the ladder as the Marine Corps used them was to box in enemy formations , some marines depending upon circumstances would shoot the lower , while others would shoot higher. Thus you box them in. While on the offensive the ladder would be lowered and they used the combat sight, now when you attach a bayonet to a rifle it will pull the rifle down

Thanks so much for sharing this. Incredibly helpful. Its hard to find good data on the ladder sight system since the 03a3 appears to be more popular. I inherited a ladder sight model a few years back and really like it! Not bad for over 100 years old.

You’re welcome. Thanks for watching! My next M1903 video will be about fitting my bottom metal to the stock. It has an issue with the follower coming out over the top back of the magazine in front of the bolt due to a gap between the action and the bottom metal.

Had my gramps 1903 for 30yrs and had no idea it adj for spin both down and up thanks you are the Man !!!!!!! Only comment I have is in my world @ 300yds a "single" shot does not a group make 30-06 iron sights 1ft spread 500 yrds is only accomplished by 5% or less of shooters. not saying that is not you just saying single shots would be questionable for the average Joe and would like to see a 10shot group @300yrds with the rifle in question as a base. warp/hot spot / hard spot/ bedding / ammo variations all would be found.

Thanks for watching! I need ti check that video again. I don’t think I tried it at 300 yet. But I seem to use a lot of 3-4 shot groups in various things I do. But to really drill down 10 is better.

I'll never sell. They will stay with family.

I thought the correct sight picture for the M1903 was a 6 O'clock hold not center mass? But that's damn great shooting though.

@yourarsenaladvisor Жыл бұрын

I think the 1903 would be set up for shooting center hold. Not really set up per se, but intended for use by aiming with a center hold. With center hold you don’t need to know the size of your target and where a particular 6 OClock aiming point is from target to target. I think 6oclock hood is for match shooting where you know the diameters of the aiming black and known distances the targets are at. It allows one to clearly see the whole aiming black as a proper full circle instead of half a circle with the front sight obscuring it. The difference is just an offset of half a diameter of the aiming black. One would just have to remember their offset and aim below that amount from whatever actual point they want to hit. I’m always shooting at different things and different ranges so I stick with center hold and focus on adjusting my sites for that.

Is the ladder sight model of 1903 considered a different model or designation than the typical 1903a3 with the rear sight mounted on top of the rear of the receiver?

Yes. It is the type of sight that came on the original 1903s before subsequent model changes.

@jeremykaleschenkoikov6993 mine has the same sight and base as the video's creator, but is a Mark 1 and is in the 1 million range. I learned a lot of these rifles were refitted during snd after WW2, so some have the later stocks and parkerized parts, but may still have blued receivers. Mine is a 1919 made rifle but has a 42 barrel on it.

If I wanted to put these on a lever rifle, what caliber would give me the most consistency.

@yourarsenaladvisor 4 ай бұрын

See this video: kzfaq.info/get/bejne/iLudmth-vuCwdJc.html You will be able to see that this sight is only the particular one designed and manufactured for the M1903 Springfield bolt action rifle. Consistency in a rifle's performance will be a combination of the barrel and projectile and some other aspects of each rifle. So your sighting systems helps you aim whatever performance the underlying rifle has within it. If you like a ladder sight you probably would need to research other different types of rifles(Lever Actions you may be interested in) to see what options are available.

@yourarsenaladvisor 3 ай бұрын

I flipped my ladder sight up and the only notches or peeps you look through are on the slider. The upper most notch is for the very top ranges since the slider has to stay in the track. The lower area can be used above so I think that is what the upper notch is for (when the ladder is up). When the ladder is down you see another notch perpendicular to the ones that is more like a battle sight already set for spin drift and 547 yds. I don’t think the top of the ladder goes to 3000, maybe 2850. So you might have one where someone added a notch. Does it look like it followed the spin drift track?

@kibbeystovall7546 Жыл бұрын

While the M1903 rear sight has lots of aiming apertures/notches, the biggest problem with using it as a target sight is the fact of its infinite adjustability. There are no "clicks" or notches to make reliable minor adjustments once you start dialing it in. It's reasonably OK for trying to hit man-sized targets at range where using the closest line should be good enough, but if you are trying to put the bullet in the bullseye at 600 yards it's much harder to fine tune it. For example, if you put the aperture/notch of your choice at the sight's 600 yd setting but find yourself shooting about 6" lower (~1 MOA) than your intended impact point, how do you loosen the aperture slide and move it reliably just that 1 MOA worth of height you need? You pretty much cannot do it without a specialized tool. Target shooters in the M1903's heyday used mechanical sight tools to solve this problem. www.ssusa.org/content/the-early-history-of-sight-micrometers/

@yourarsenaladvisor Жыл бұрын

I agree. The graduations for windage are just too large of a movement per the scale provided. I think it would be too hard to mark it to measure various settings without other tools to show one where the based moved, etc. I figure match shooters would have to rely on windage holdovers. I think elevation might be easier on the ladder to try and write down various data due to all the various numbers and lines. Thanks for sharing!
