I have a question for some of the Ross rifle owners regaurding adjusting the sights. I have a model 1910 ross that shoots great but it was shooting left, to get point of aim and point of impact to line up I had to move the rear sight 2 1/2 lines to the right. This is fine but the peep hole in the rear sight is now slightly blocked by the plate behind and is interrupting my view a little. The front sight is centered right now.

My question is to correct this should I move the front sight to the right so I can move the rear to the left? If I want my rear sight lined up with the 0 I'm guessing I would have to move the front sight that distance over to the right to correct the problem? What I'm getting at is to move the front sight over that far would make it way to the right and make it sit all the way right in the sight hood.
I'm guessing that the entire front sight base could also be moved over but I'm not to sure what the proper way to do this would be without damaging my prized possession. Any suggestions would be great, I'm just wondering if there may be a solution to the problem and that maybe I can have my sights centered the way they're supposed to be.

That's the thing I've moved the front sight before but the problem is I'll have to move it way over to get it to where the rear sight is even close to being centered. I guess what I was wondering is how hard is it to move the front sight base over on a Ross? Maybe I'm asking too much from a 100 year old gun and if I have to live with it I will but it would be nice to be able to adjust the sight left or right on those blustery Manitoba days where the wind is screaming.
 
Here's some pics.

Here's the rear sight, notice on the bottom right of the hole is slightly blocked.

And the front sight.

Just nudge your front sight a little to the left.A bit at the front is a lot less than a whack to the right at the back.You have to remember that you are looking at your front sight down ?? maybe 25" inches of barrel.Your front sight to me looks a bit to the right.1/64 of a inch off will throw you quite a bit off target.Centre your rear aperture on your front sight and adjust your front sight until you are centre of target.Unless you have bedding problems or perhaps a slightly bent barrel this should get you on paper.What range are you shooting at?You have it cranked pretty low,Try sighting in at 100 yards with a large 4'x4' peice of cardboard and see what your point of impact is.
 
Crown look's good, but as stated abouve your front sight need's a moving.
Loosen the screw on the front of the sight base and it should move quite easily.
I like to flood such area's with oil a couple day's before I try to move them, when I get them apart remove the screw ad oil the screw itself and the sight base.
Same if you decide to remove the sight hood.
 
Thanks for all of the help guys. I thought I had it @ 100 but with a magnifying glass it's reads 0!! I never realized that you can adjust the tension on the rear sights themselves either. Found that on this handy internet thing from a post by Buffdog. I moved the front sight over a 1/16th and then cleaned/oil all of the rear sight pieces. I also tightened the screw, now it's snug and holds it's position but can still be turned. The rear sight was so loose that Im guessing it was backing off when being shot and therefore kept hitting the bottom to the 0 mark. I'm still a newbie, this is only my first year of shooting and I guess the sights on a Ross are great in the right skilled hands. I've only been shooting @ 75 yards and after looking at my targets I was indeed hitting low. thanks for all of the help, can't wait for the weekend so I can mess around with her some more!
 
The problem is the Brits bucked the barrels off without adjusting the sights. A sight that was positioned for a sight radius of 36 inches or so isn't going to align if the radius is suddenly reduced to 26! The sight is marked to correspond to the original radius and the trajectory curve of .303 MkVII ammo.

If you shorten the barrel, every adjustment of the sight will be larger on the target by at least the percentage by which the barrel was shortened, and that doesn't even take into account trajectory. In other words, even if the bullet travelled like a laser in a perfectly straight line, which .303 MkVII certainly does not, the original sight markings are useless once the barrel is shortened.

But of course these were only intended to be hunting rifles for Joe Average, zeroed at one range, if at all.

Thanks for the info. My barrel is full length so I'm guessing the sights should be close to right on. I didn't end up pulling the Ross out this weekend, to cold/windy plus I bought a long branch and spent a little while shooting that.
Hopefully the weather next weekend will be better and I can spend some time working on a load for the Ross as well as getting the sights tuned up.
