Mosin Accuracy with and without bayonet?

Very interesting point of view!
So based on it anything on the barrel will change accuracy because of vibration?
So best solution would be this:
"The Remington 700 and the Lee Enfield rifle use up pressure at the fore end tip of the stock to dampen and control barrel vibrations."
I understand concept of "freefloting" barrel.
Thank you.



A rifle barrel when fired will flex and vibrate like a tuning fork, there are many ways to control barrel vibrations and thus accuracy. The bayonet can alter the way the barrel vibrates and effect POI and accuracy or group size.

On some rifles the barrel has steps cut in the barrel at the vibration node points to control barrel vibration and thus accuracy.

The .22 rim fire rifle below has two barrel tuners attached to the barrel to control barrel vibrations and accuracy.

Please note the one hole bug size groups fired from this highly tuned rifle.

Another rifle with an adjustable weight mounted to the end of the barrel and like a bayont will change the POI and group size. ;)

Taunting Koala bears and Roos can be hard to see and hit at night without the right equipment. :eek:

So I see a lot of you have 91/44 model and and my opinion is a bit different from 91/30.
44 model was tested with bayonet but as far as I know 91/30 was not.
Considering both rifles are in good shape which is more accurate with bayonets attached or detached?
And based on your observation little adjustment makes as accurate with bayonet detached?
 
When my hunting partner wrapped his barrel in camo tape it threw his point of impact off by a huge margin.

Harmonics plays a big part so if tape will do it I'm sure a bayonet will.
 
From what I know they were made in two different places and then attached to rifle.
As in regards to scabbards, bayo usually were sitting on the belt. Just hanging there upside down.
In any case your theory has a point and made laugh. :D:D:D
Thank you

The 91/30 was sighted with the bayo attached & it was meant to be left that way. Ever wonder why you never see soviet bayonet scabbards?

Well, it was only supposed to be removed for cleaning but you know what they say " There is the way it supposed to be & then there is the way it is.".
 
Without a bayonet, at 100m, my 1931 manufactured Russian 1891/30 Mosin Nagant shoots two inches high and two inches left. With the bayonet on, it shoots dead center.

Without a bayonet, at 100m, my 1951 manufactured Polish M44 shoots one inch high and an inch left. With the bayonet on, it shoots dead center.

FWIW - my SKS and the SVT-40 shoot dead center without the bayonet. No change in either with the bayonet deployed.
 
My 91/30's all shoot high and right without bayo too. I raised the front sight post on my first 91/30 and pushed the sight quite a bit to the right. Now it's spot on at 100 yds. I raised the post excessively high and use the rear sight to control elevation.

I've encountered 91/30 front sights that are different and won't allow me to do this mod. I ordered some of these bad boys from Josh Smith and will be using them soon.

What did you do to extend the front post? Did you just slip some tubing over it and crimp it in place?
 
I just can't see shooting my MN with the bayonet fixed. Without it I found that the hits were high and to the right. To get around this I made up a new taller front sight pin. And when replacing the base in the dovetail I centered it instead of the way it was bumped slightly to the left.

I was going to "tune" it with a small needle file and some further front mount bumping but so far my guesstimate of making it around 1/16 inch taller and centering the front seems to be paying off with the last few rounds I had seeming to give decently centered shots at 100 yards.

Mind you I only had 6 rounds to try it with. Gotta get a couple o' spam cans to carry on with the fun.
 
Maybe for the 91/30 I have never tried it with that model so I can not say from experience.
However, I have tried it with my Russian M44 at 100 meters.
I shot 10 rounds and my groups were centered on my point of aim with the bayonet folded.
With bayonet extended and another 10 rounds, my groups were actualy off center to the right considerably.
 
Can't even mount my bayonet; I've succeeded in acquiring one of the rare faulty ones with the slot too narrow to allow it to turn into place.

Shooting without it was definitely drifting left and low. I can ring a 6" gong at 100 yards 4 shots out of 5, so it is fairly accurate as a war rifle.
