Mauser and Mosin shooting high

[DavidB2]

I am having a hard time with both my Yugo Mauser and my Mosin both shooting high. I have been moving the slide adjustment forward so that the rear sight raises. That is what I thought you were supposed to do, isn't it; adjust the rear sight up if your rifle is shooting high? Perhaps I did not adjust it enough. I ran out of ammo; so I could not stay at the range. Also, despite much scrubbing with brushes and cleaning out all the cosmoline with brake cleaner; I am still having my bolts stick on both my 31/90 and M44. I am also using Wolf ammo, which I believe is brass. Any suggestions on that issue is appreciated as well.

That's opposite of what you need to do.

Bullet impact will FOLLOW the rear sight. i.e., move the rear sight up and the bullet will strike higher. Move it down and the bullet goes lower. Move it left and impact shifts left and move it right to move impact right.

OTOH, bullet impact will go opposite of a change of the front sight. A higher front sight will lower the bullet impact and moving it left will cause impact to move right.

Also a pretty basic technique that you probably already know, but use a 6 o'clock sight picture. Set the "x" or whatever you're shooting at on top of your front sight. That might bring your groups down a bit too.

My Mosin shoots right, about 3 inches at 50 yards (ouch). Just remember to adjust your irons the opposite way you want the bullet to travel, like tilling a boat, left is right (windage), up is down (elevation), etc.

Let's recap:

Move the rear sight in the direction you want the bullet to go.

Move the front sight in the opposite direction to the desired point of impact.

Most military rifles of that era were sighted to shoot high -- the idea being to get as much range out of the battlesight setting as possible.

The cure is to replace the front sight with a taller sight or build it up with welding, epoxy, etc.

Is the bolt sticking when you are extracting the fired case or are they just sticking on an empty chamber?
If it's sticking cases, then you have not got the chamber clean yet. Use a brass shotgun brush in a drill with an extension and use the cleaner to keep it wet. Eventually you'll get it clean. That dried cosmoline can be real stubborn.

F.O.R.S easy to remember
Front Opposite,
Rear Same.

mosins and mausers are made to shoot out several hundred yards. if your shooting at 50 yards, its going to hit high. thats just how its factory zeroed. shoot at longer ranges
