First time owner trying to get my mosin up to par (and myself)

[Vrax]

Hey SH,

I recently bought a mosin 91/30 from budsguns.
I cleaned the heck out of it, top to bottom, took it all the way apart and reassembled it so that I'd know my way around it and would not miss any of the gunk they use to store it.
I took it to the range with a can of silver tip surplus ammo.
I can see the draw of it and why so many people love it. But mine needs some help.
Problem #1 is that it shoots WAY off. Low and to the right by 2-3 feet at 100 yards. I tried moving the front sight, but it's frozen, and I don't want to bend or break the front sight pin.
I bought the following things to try and get around it.

So far so good. I didn't need the iron sites anyway....
Now my issue is that my own head moves around, and this LER scope's crosshairs move with it.
Any suggestions on a cheek rest for this rifle, or ways to shoot to NOT move my head all around? I'm a tall guy with long arms, and the stock is small for me as it is.

Thanks for the feedback, any and all is appreciated.

This is for those who want to keep their Mosin "as issued" and legal for the CMP GSM rules.

The windage is corrected by drifting the front sight left or right.

Elevation, most are too high. You indicated yours shoots low. File some off the front sight. How Much???

Lets say your shooting 100 yards. take the sight radius and devide the sight radius by the range (in inches).

That tells you how much you need to adjust the sight to move the impact 1 inch.

Mine shot 8 inches high at 100 yards. I measured my sight radius and came up with 22 inches. So I divided 22 by 3600 (100 yards times 36) and I got .0061. .0061 X 8 = .04888. I then removed .0488 from the bottom of the slider (on the ladder sight) and put me right on at 100. Which was also on at 200, 300, 400, etc when I set the sight at the repective setting.

This works for elevation, up or down and windage left and right.

If I was shooting low I would have cut down the front sight .04888, but since I was shooting high I had to lower the rear sight.

To do this without ruining the "as issued" effect. I took the sight off the rifle. Its ladder type sight. I milled .0488 (or .0061 per inch) so the sight would set that much lower on the sight base.

It works.

Since I shot CMP GSM matches I can't add anything to the stock. I just adjust the stock on my shoulder so I get the cheek weld I needed. Keep the head straight, bring the rifle to the head, not the head to the rifle. With practice, it can be done.

Get a bigger hammer to drift the sight whilst the rifle's otherwise totally immobilized.
The comb of a mosin stock is so low already, scoping it to begin with is asking for problems with sight picture. But you add a see-through base, and see through rings on top of it and I can imagine why you're having trouble. I know options are limited when scoping the mosin, but if you can, change the base and/or rings if you have clearance to lower the scope. Get the cheek pad but for now try draping a sweatshirt over the stock when at the bench or prone. I do it all the time as it helps deaden most of my own shaking. There are rubber buttpads available that'll add an inch or so to the Mosin's length of pull. A slip-over recoil pad will add more if it's still too short. Monte-carlo style stock could also be an option.

I think a basic approach to stuck front sights, pins, etc. with the Mosin is some soaking with a good penetrating oil, like PB Blaster, etc. I find it can take days with some pins.

The scope you've ordered is a good one, but it has a normal eye relief. This will not be useful with a Scout type mount. I have also tried the Bushnell banner 6" eye relief scope, and even that length of eye relief is not enough. You really do need an LER (Long Eye Relief) scope for the Scout mounted application. https://www.google.com/webhp?source....r_qf.&bvm=bv.43828540,d.dmg&biw=1920&bih=897

See-thru mounts are high. You will need some form of additional cheek rest support. The lower the mount/rings, the better.

I am in the process of doing what you have in mind, and have started a thread with my experiences so far. http://www.snipershide.com/shooting/showthread.php?t=116641

I have found that all the items I have found a use for so far are available from Amazon, using the search word "Mosin".

Thanks for all the input!
I'll be taking it back to the range tomorrow to do some more testing.
I'll work some oil into the front sight over the next few weeks and try some more taps.
As for the mount and scope, I'm stuck with them for now, so I'll use them to the best of my ability, though I think I'll buy another mosin to keep stock and learn the iron sights better.
God bless surplus ammo!
