on the sea. very near the bears.
I bought this rifle years ago and thought I should get it
sighted in. I fired 2x3 round groups(iron sights) and was a little dismayed to
see it was shooting 10 to 12 inches high. I remembered reading
on this forum that the 91/30 was sighted in with the bayaonet attached.
So.... I attached the bayo. and yes...the point of impact at 110 yards was
only 4 inches high. More work to do on this, but I am encouraged.
Anyone else have a similar situation?
 
Everyone I have ever seen is basically like this. They usually shoot 6 inches to the left or right as well (Can't remember which way specifically).
 
Mosin Nagant rifles were sighted in with the bayonet attached, by the best shooters in the unit. In the Red Army, the bayo was expected to be fixed at all times unless it was totally impractical to do so (such as in vehicles). If the bayo wasn't fixed, the only way the Red Army wanted it carried was upside down on the left side of the rifle. That's why you never see scabbards for the Mosin Nagant bayo, the Red Army issued only a very few!

4" high at 110 yds sounds about right, possibly a bit low. IIRC the rifle was sighted in at 100 meters with 4 shots. The rear sight was set to 300 meters and the shooter aimed at the bottom of a black square on the target, which was about 12" tall x 8" wide. The required mean point of impact was about 6 3/4" above the point of aim. The rifles' zero was confirmed if the 4 rounds fell into a 5.9" circle. The average center of the group had to be within 2" of the point of aim.

This sighting in procedure was consistent with Red Army doctrine to aim at the belt buckle of the oncoming enemy.

I just can't imagine going to the range with the bayo attached.
I think some folks would wonder.......wtf?

I do it all the time, nobody cares & it hit where its supposed to. BTW I read somewhere soviet doctrine called for poi three inches higher than poa at 100 meters with bayo attached.
 
Shredder, thanks for that info!
Part of the fun with these milsurp rifles is their history.
Would you get the same grouping if you attached the bayo on the
left side (as in de-activated, for lack of a better word). Do you think the
issue is simply the weight of the bayo, or is it more to do with the leverage
of the overall extended bayo that pulls the poi downward?
sorry for this nerdy question. but I would like to know.

I honestly can't answer your questions, as I've never tried it (bayo backwards).

I suspect, but can't prove, that having the bayo extended dampens barrel vibration, thus enhancing accuracy from shot to shot.

Gotta remember, most of these surplus Mosins saw very, very hard use on the Eastern Front in WWII. I'm not surprised that some of them just don't shoot accurately, as the barrel is likely to be worn out.
 
my hex mosin was shooting 22 inches high at 100 yards. I couldn't figure out where my bullets were going until I hung a huge chunk of cardboard up and finally figured it out. I figure the front sight is way to low although it doesn't look like it is.
finally scoped it and it has improved although more is needed to fine tune.
 
I squeezed a piece of old brake line over the front sight of mine and filed to proper hight. Of coarse you could leave the bayonet on and roast hot dogs and marshmallows with it after a shoot for the boys
