hello

I am just wondering how the cut barrel will effect the sight on my ross or really any mill surp. here is a pic of my guns. all are different lengths. so how do I set the sights at each distance? or will it make a difference ? if I get a taller or shorter front sight can that compensate?

if I had them all zero for 100 or 200 yards were would I place the battle sight mark on?

 
If the military front sight is set back, the rifle will shoot a little lower due to the taper of the barrel. Since military rifles tend to shoot high at ranges around 100 yards, that is not necessarily a bad thing.
 
by shortening the barre on an iron sight rifle, you affect the sight in 2 ways:

1. you shorten the sight radius, which means that the angle between the sight line and barrel gets steeper, or to put it another way, the bullet is going at a more upward trajectory at the same sight setting.

2. you reduce the muzzle velocity, which means that all the original range markings on the sight are wrong.


to correct 1, you would get a taller front sight, or use a shorter range setting on the rear sight. the amount will vary based on how much is cut, original sight radius, ammo, etc. any change to the sight adjustment will be exagerated from before.

to correct 2, you need to use a lighter bullet which will allow higher velocity, but will throw a further wrench into your original range markings, or do the opposite from 1, shorter front sight, or longer range setting on the rear sight. the range markings will still be wrong

this gets tricky as you are changing a lot of variables. if you are lucky, the sight settings wont change at all, this would work if the velocity loss had an equal and opposite effect of the now exaggerated angle of the sights. more than likley you will need to change the front sight to taller or shorter
 
okay thanks. at least its pretty easy to change the front sight on the ross. I will try that first. all the ammo I have is a surplus of WW2 Canadian stuff. so I wouldn't want to mess with the loadings.
 
My Ross has a chopped barrel, and I just can't seem to hit paper at any range. The bore on it is quite good. too. I was wondering about the sights being screwy due to it being shortened, I guess I am in the same boat.
 
I had a full length Ross with a puked bore. Puked as in disintegrating due to corrosive ammo in it's history.

The bullets were keyholing at 25 yards....sad case indeed.

The more you cleaned it...the more metal came out with every stroke.

Hopefully yours isn't like that.

You should slug the bore and see what diameter it is. Some Enfields are way oversize and benefit greatly from oversized cast bullets. (per Steve Redgewell)
 
Some Rosses are pretty oversized too. I had one that was .315

JTF, are you going to restore that bottom one? I see enough parts there to do it, you just need a little wood!

I bought a Ross M10 from Flying Pig last summer. Even though the barrel was shortened, it shoots remarkably well with the original military sights. It shoots best with the sight ladder raised and using the peep at the lowest possible setting. If the ladder is down and I shoot using the sight that way, the gun shoots 12 to 14 inches high at 100 yards. Still groups well but way high. I shoot both factory ammo- (Remington), reloaded ammo with 174 gr hornady RN bullets and cast lead 180 gr bullets. Try the peep with the ladder raised and see if it is on the paper. Be sure to set it as low as possible.
 
The nosecap on that top rifle of the 3...too bad there's no bayonet lug on it. :(

It looks a bit small but has the cross screw.

It almost looks like the size of a Cadet cap, but as I recall they didn't have the cross screw.

Looks like some dents on it?

Would love to see some more pics of it including whether the bayo lug was removed and if the 2 screws are there.
 
I want to restore it but only if i can splice the stock because it is marked to the 15th CEF. I wouldn't restock it. I was thinking of doing a sniper rifle out of it and I have seen all kinds of the old scope even ones that were meant for the 1903 rifle but I have never seen the side mount that attaches it to the ross.

Splices can be done. I've done a couple and others on here have too.

A fellow I did a stock for in the UK managed to have a mount made for a W&S scope for his. Problem with the scopes is they are basically only to look at, they are nearly impossible to fix if damaged.
 
I agree with that. they are not very strong scopes. that's why I wouldn't be scared to put a 1903 scope on my gun if it was in working order. its not 100% correct but at least it would be fun to shoot

how would you splice a stock? if this something you know how to do well? I have the nose cap on the other gun I could maybe switch to my main gun?
 
I can do a pretty decent job of it. The splice will never be as strong as it was originally, but they work. I have a set up for my lathe that allows me to get the dowel pretty straight, which is the tough part.

If it were mine I`d clean it up and leave it as is.

You`ll never prove it, but it could have been like that since WW1.

Not all sniping was with scopes, the trenches were often less than two hundred yards apart in places.
 
thats right there was a pic that someone posted on here of a group of Canadian snipers in ww1 all the Ross rifles were cut in that exact same way.It wasent done at the factory but by field armores i think
