Mosin 91/30 Front Sight Elevation Adjustmant?

[concretus]

Hello All,
I've decided to jump into the ring of Milsurp bolt rifles (again) and purchased a M91/30 w/ laminated stock. I have a couple of 03A3 Springfields but they've been converted into a target and hunting rifle(best hunting rifle I have). I know I'll probably get struck by lightning by the gods for converting those rifles but the Mosin, I plan leaving alone. I haven't received it yet (this weekend) but I can see the front sight is adjustable foir windage by drifting the base. is it also adjustable for elevation? The rifle club here has milsurp shoots at 200yds and I wanted to use the Mosin. Do they make longer front sight posts if needed?
I've seen in You Tube that some people have relieved wood to "free float the barrel w/ a piece of cork gasket material in the front to give a little upward pressure to the barrel. Just out of curiosity, has anyone ever glass bedded the action to the stock?
As far as using milsurp ammo w/ corrosive primers, I guess windex or soapy water is the treatment to remove the salts, correct? Any other methods? What kind of accuracy are folks here getting with them? Anybody handloading for it? Any recipies? Maybe one day I reload for it. Thanks...

I've heard of guys using black electrical wiring insulation over the front sight post to make it taller. Find the right size wire, strip off a little bit, slip over the post and cut to length.

We do a laser welding job on the frontsight. Add 1mm and if it was to much, a bit of grinding down and all is ok. For the accuracy, my comrade is able to hold around 50mm at 100yards from an sandbag and he use the VV N110 with FMJBT`s. For the bedding you can do it the same way as in other milsurp rifles too.

Regards

1. Many M/N's shoot high at 100 yards. I tried slipping the insulation over the front sight but the additional width didn't look right for me. I (ever so carefully) filed the sliding rear sight base, and the metal it touched at the minimum setting and reblued it.
2. I have not tried the cork trick yet. My Finn M39 is freefloated and it out shoots both M91/30's and an M44.
3. The "salts" are water soluable - hot water works well followed by a finishing touch of whatever you use for normal cleaning.
4. Most of what I learned about M/N's came from: 7.62x54r.net
5. Enjoy! -Aim High

Thanks everybody for the information....

I used a piece of black heat shrink tubing. Cut it off just about 1/16 inch above the front sight. Nobody has noticed it yet unless I mention it. The tubing shrinks to one-half of its original diameter when heated with heat gun or match. The best part is that it is removable and will not damage the rifle in any way.
Have fun with it. Mine is a lot of fun and more accurate than I expected.

Reloading information is avaialble on the Hodgdon powder website Hodgdon - The Gun Powder People

I have used the Hornady 150 grain .311 diameter bullet in my son's Mosin with good success. Reloading is easy, gives the quality control to you, no issues with corrosive ammuntion, and in the long run is substanially less expensive than factory or milsurp ammo. Some of the 7.62x54r ammo I bought as surplus was in fact rejects. After having to use a rubber mallet to open the bolt when using the ammo in my SVT-40, I pulled bullets and weighed the charges, great deal of varience in powder weight as well as seating depth of the bullet.

What was the powder you used, thecharge weight, brass and primer did you use

I don't recall. I will post the details here when I get home this evening. GRF

I used the 150 grain Hornady bullet .312 diameter designed for the .303 over top of 52 grains of IMR4350 in a graf and sons case with a federal large rifle primer. This load should replicate WW2 ammunition velocities of about 2650 fps. 5 shot groups at 100 yards ran 2.35"-4.5" with an average of around 3 inches.

There is reloading information for the 7.62x54r in the Hornady and Seirra manuals, sometimes listed for .308 diameter bullets, although all of the factory / surplus ammo I have measured use .311 to.312 diameter bullets.

It is very important before beginning reloading to check a variety of properly vetted sources, the aforementioned Hornady website, the most recent Hornady, Seirra and Lyman manuals are good places to start.

We have also had good luck with privi partisan and igman factory 7.62x54r in my SVT-40.
