    Mosin zero?

    I’m looking to get my Mosin out for the first time tomorrow and hope to zero it for 100m. If I'm zeroing on a 25m target using a 180gr bullet, how high above my POA should my POI be for a 100m zero? I've used a ballistic program to try and figure it out and i'm getting about .49in but having never really used one to figure out a zero on a 25m target, I don't really feel confident in my math.

    I know the Mosins tend to shoot way high at 100 m with the original sight and modern ammo.
    I had to change the front sight and install an adjustable one.
    If I’m not wrong, i shot between 8 and 10 inches high with factory ammo from S&B.

    I have a replacement adjustable front sight from Smith-Sights, so that’s not really a concern.

    Only if you don't have the bayonet on it. My M38 (designed not to have a bayonet on it) shoots to POI, and my M91/30 does the same provided the bayonet is on it.

    If I’d go with the bayonet to the range I would be liable and probably arrested.
    Other laws here over the pond.
    My M44 shoots low, but my 91/30, like the others I tried (always without bayo), all shot between 8 and 10 inches high at 100 meters.
    I installed an adjustable front sight, exactly like the original one in the looks, and am happy since then.
    From Euclidean Machine in Canadaicon. Very nice guy.

    You have laws against having bayonets on your rifles when shooting? Weird

    But true...
    They probably make the guns more dangerous
    Our bayos are also all registered as weapons, whereas a butcher’s knife is not.
    A no. 4 spike bayo is a war weapon, my butcher’s knives with 10 or 12 inch blades are not.
    That happens when people with no clue have to legislate upon things they don’t know and don’t give a damn about.
    I actually shot the M44 with the bayonet folded and unfolded (had to wait for a day with no-one else there). The POI moved roughly 4 inches to the right, but I can’t recall any noticeable elevation difference.

    The bayonet will only effect the POI when the gun is fired by a inexperienced shooter with poor form . If you do not hold the rifle correctly to manage the recoil , the weight of the bayo will hold down the muzzle climb . The bayo has never made a difference with any of the good shooters I have seen ,nor any of my 80 Mosins . Another internet myth is that a Mosin " has the barrel "" tuned "" for the bayonet " and shoots better with it on the rifle . Facts : any movable , vibrating weight on the barrel is bad for accuracy . Mosin's were designed to be made quickly and in large numbers , the barrel has a convex mating surface and is screwed in until the rear sight base is close to the top . The resulting barrel pressure with vary from 25 to 250 lbs [ on the ones I have removed barrels from ] , not hardly " tuned " . Russianicon snipers did not shoot with bayo's on , a lot of their snipers had non scoped rifles .

    It was doctrine that the majority of rifles (i.e. Dragoons, Infantry Rifles, M91/30s, etc.) were sighted in with the bayonets mounted. If you don't believe having a bayonet mounted makes a difference, you likely haven't shot a rifle with or without a bayonet, as it most definitely changes POI (and there has been many attempts to mitigate those effects throughout history, if it didn't have a effect militaries would have ignored it as opposed to doing things like the M95 Stutzen bayonets with a sight mounted on the bayonet, or changing mounting techniques like the Germans removing the muzzle ring). Inexperience has nothing to do with it, the barrel harmonics, and how the bayonet is mounted does.

    I can't even believe I have to try and explain this concept.

    The problem is that shooting with a boyonet or anything else hanging off the barrel is going to produce inconsistent barrel harmonics. I’m sure doctrine was to shoot with boyonets mounted but it’s never going to give you consistent accuracy...

    Now back to my original question.
