Innacurate Mosin

Does anyone have a clue why my shots at 75 yards are hitting way high and about 10 inches to the right? Im taking very steady shots, no flinching, no wind, prone position with a bipod and i have to aim at the very bottom left corner just to hit the top right corner. Why is this? Its really bringin me down because everyone else praises the mosins and mine cant even hold a group of under 5 MOA! Might the shots be hitting right because im not shooting with the bayonet attatched? I put a new post on the front sight made out of a pen ink tube thing and raised it up a lot but its still hitting high. Help!

Did you make sure that both of the action screws were tight? Loose screws=a bad day at the range.

yes i did. and my theory was proved wrong. i attatched the bayonet and made a little taller front sight but the shots wouldnt even hit the paper this time.

Lots of Mosins seem to shoot high. That can be cured by slipping a split pin over the front sight. Then file away until you're shooting inline with the 10 ring. The windage is just a matter of taking a hammer and drift or punch and moving the fore sight until your rifle is centered. If your groups are still unacceptable large then either assume you got a lemon or lie about them. I suspect that both options are used more then one might think.

My groups with iron sights are about the size of a pie tin at 100 yds and I've just accepted that that's the best I can do.

My front sight wont drift. Ive heated it and pounded it with a punch and everything i can think of but it wont budge AT ALL. Im thinkin about just traidin it off for somethin else or some cash.

Well it could also depend on what kind of ammo you are using. Generally speaking, the milsurp stuff, Czech, Russian or Bulgarian really isn't bad stuff. Try "corking" your MN rifle. Cut a small piece of cork material, or gasket material to fit between your nosecap and barrel. A slight bit of upward pressure can help improve accuracy. Run a piece of paper under your barrel to see if there are any pressure points created by the stock on the barrel. If one or two pieces of cork material don't make it slide without any interruptions, then you might want to try sanding the barrel channel in the stock. Or you could try shooting with your handguard off in case the barrel bands are squeezing too tight around the barrel. It also depends on your bore too. If its still got strong lands and grooves then it ought to be grouping better than 5 MOA at 75 yds. Kinda sounds like my 1943 M44 when I got it. Was shooting all over. I sanded out the barrel channel of the stock, and corked the nosecap and barrel and it dramatically improved accuracy. I just completed a few "accurizing" tips for MN rifles that I have published to YT.

Here is the direct link to the video. If that doesn't work, go to my channel at YouTube - MarshalZhukov's Channel and you can find the vids there.

i use the czech 1980s 147 grain light ball steel core ammo. and all of the tips in your video are great but i dont see how they could tighten up my groups from not even hitting the target to getting MOA groups. I will give it a try though and give the results!

Use a bigger target at shorter distances! That should improve your hit/miss ratio. LOL

that shouldnt be needed though. for a rifle capable of shooting up to 1000 yards, i think i should be able to fit my shots on a piece of computer paper

I have to drift the sights on my mosins to center it up. Maybe hit it with a bigger hammer

Yea man, try that stuff out. But if your bore is strong, then that is very odd. You might try shooting some commercially loaded stuff if you're not pinching pennies and see if that is any different, or another type of milsurp ammo. My m44 was all over before I did it, and the next time I shot it, it was like night and day.

That is very interesting. I have never had a problem drifting any of the front sights on the rifle. Maybe a little heat may be necessary?

Must have missed that part about the heat. That is very odd. I don't know of any MN front sights that were soldered in place. Hopefully the situation can be resolved.

rifleman, exactly how are you trying to move the front sight on that mosin anyway? and which direction are you trying to move it? (looking at it from the chamber)

Is this M44 you're shooting?

How is your bipod attached?

Can you post a picture?

Have your tried soaking the front sight in penetrating oil for a day before you attempt to drift it? I've never found a Mosin front sight so tight it couldn't be drifted, but I've used the same technique on nuts that simply would not turn that had to be removed. I'd recommend Marvel Mystery Oil if you decide to try it.

To heck with all this drift and cork stuff. If your rifle is shooting 10" high a 6 to the right just move your target up 10" and 6" to the right and aim at the same place!


Sorry, all the good advice has already been said!
