    Shooting help

    Hi guys,

    Was shooting a Mosin Nagant at Deer Stalker range and can't for the life of me work out what is going on. My guess is that someone has filed the front sight peg too low.

    If I shoot the gun on a rest @50m it shoots about 4 inches high. That is with the factory slide sight all the way to the back. If I then fire it at 100m it never hits target. I have tried aiming at the bottom at the top of the target to see if i can get a hit. If it is 4" high at 50m where would one expect it to hit at the 100m? Low or High?

    Cheers,
    RS

    I had a carbine back in the 80's, from mem doesn't the front sight screw up and down? I think they were issued with a funny looking key thing with 2 prongs on it but then again I could be mistaking it for an SKS etc...

    The sights are factory set at 300m IIRC. One trick was to strip some wire and use the sheathing to slip over the front site then snip it down to calibrate it.

    Hell I was lucky with mine in terms of elevation (no bayonet).
    Set the rear sight to 100 and with Privi factory ammo it was 3" high and 4 inches right at 100m first time I shot it.
    Windage will be solved with a hammer and punch!

    Depending on model ie 98 or 98/30 the sight should be an inverted v without a shroud or a straight post and shroud. Simplest way I found to alter it was silver solder to build it up and and file it down.
    The std rifles start at 300 metres though finnish ones sometimes have a 200 m cut into the slide
    With the carbine with fixed bayonet the sights were calibrated for that taking the bayonet off changes the poi badly

    My 42 Izhevsk is great. Shoots a little to the right but I think the bayonet fixes that.

    What year and factory is yours rs200nz?

    It'll possibly need building up, not shaving down!

    What ammo were you using in my model 91 the Barnaul 203 gr shoots 3 1/2 low and the 150gr 2 1/2 high at 100 m or should that be arshins.
    In my carbine the same ammo is dead on and 5 high respectively.
    Had some Yugo fmj a while back and they shot 3 high in both rifles. I have no idea what the projectile weight was.

    Hello,

    The 91/30 was sighted with the bayonet affixed. It will therefore shoot high and possible a bit off to one side with the bayonet removed due to a difference in barrel harmonics. (If it helps, consider the bayonet a weight that pulls the barrel and, subsequently, the bullet holes, down.)

    Generally speaking, all 91/30 sights will have posts that are already too short due to sighing in with the bayonet affixed.

    You might be able to find one from an M38 or similar carbine that doesn't take a bayonet, but those who offer these for sale generally are not in the business of measuring posts.

    Your best bet is aftermarket. As was mentioned, some use wire insulation, but man, the resulting post is thick!

    Regards,

    Josh

    Just shot a 5.04" group with open sights with my 91/30 Mosin today, sitting on bench, unsupported with the Barnaul steel cased 203gn SPs.
    Zero is dead on with that ammo, last shot of the day was 1 inch right and 0.5 inch high, so happy as.
    Can't reload for cheaper than that ammo ($95 per 100), so would only do it to get it shooting even tighter.
