Bayonet affects M91/30 Accuracy?

Mosin-Marauder

I found a bayonet for $10 at my local gun shop. I heard a lot that the M91/30's were sighted in with their Bayonets attached and that it affected their "harmomics"? Anyway, considering my Mosin is shooting a very large group at 50/100 yards, so I would like to do anything I can to affect accuracy without modifying the rifle itself. Anyway, thanks for any help.
 
Unlike most western armies, who used bayonets which are easily attached and removed, the Mosin Nagant M91 rifles bayonets were more of a semi-permanent mounting.

Czarist, and later Soviet armies used the bayonet fixed, usually permanently.

The mounting is very tight on the barrel, and bayonets were left on, virtually all the time.

Your rifle may shoot a better group with a bayonet on it. It may not. Having a bayonet on the rifle almost always affect the point of impact. How much, or even if, it affects group size will depend on the individual gun.
 
So would picking up the Bayonet be a good investment? Even if its only $10 I dont want it to jusy gatger dust. Could I sand down the inner ring of the Bayonet so that it is easily removable and still stable?
 
The bayonet does affect barrel harmonics, but not in the way you're thinking.

It's doubtful that it'd have much affect on accuracy itself, in terms of tightening up groups, but it WILL change the point of impact with it mounted.

I wouldn't bother to buy one.
I've experimented with & without, no advantage to "with" that I saw & the bayonet's a pain to get on & off, not handy for toting the rifle around either.

The bayonet does change POI ..... several inches @ 100 yards for my "43 Izshevsk.

With the bayonet, its shoots a couple inches high and an inch right. Without, a couple low and left.

It is handy for policing up the range after shooting:

I've never had a problem removing the bayonet.... and as for toting it around, do what the Russkies did when on a train or truck: put it on backwards, so that the spike lies alongside the barrel like th M44 did later......
 
Not sure about the 91/30, but my M44 shoots different with the bayonet out vs. folded.

Is it barrel harmonics? Bayonet affecting gas dispersion pattern at the muzzle? Shifting weight past the muzzle affecting how I hold the rifle? I don't know, but there is a difference, although small.

How large a group at 100?

When I first got mine, I got 6" @ 100 yards .... then I tightened the action screws.... cut the groups in half ....

You can relieve (remove wood from) the barrel channel on the stock ...... put cork under the barrel near the front barrel band ..... google it.

Me, I'm impressed with what I have:

10 milk jugs, 100 to 200 yards, one box of Prvi Partisan 150gr soft points .... with ammo left over .....
 
it wont make your gun any more accurate, it will merely shift the point of impact.

increased accuracy does not necessary mean increased precision.
