Mosin 91/30 accuracy

[SilenceIsGolden]

ok so I have a 91/30. it does not seem to be counter-bored as far as i can tell. I had been shooting 'hunting rounds' (soft-point approx. 204grain) and hitting target at about 70yds. bought different ammo, this time mil-surp Bulgarian steel-core 146grain. at same distance not even touching target. I dont understand, would the decreased velocity cause me to shoot higher? also can anyone tell me some ways I can modify my 91/30 to max out the accuracy this rifle is capable of?

Why do you think it's lower velocity? A lighter bullet will generally shoot higher. With the factory sights my mosin shoots almost a foot high at 100 yds and any least that high at 242yds - that's the steel plate distance at my range. By holding amount 12" low and compensating for wind I can keep it on a 12" plate shooting off sand bags with iron sights. Now I just need a higher replacement front sight pin. There's several variations of these on eBay.

what kind of ammo were u shooting? 12" high wow that would explain it. ill take a look at different iron sights online and try aiming lower next time lol. thanks Ford.

This link is where a guy went into accurizing a mosin.

I tried several brands of mil surplus from 142gr to 206gr and they all shot high to some degree. I was hoping the 206's would shoot dead on but still 6" high at 242yds with the rear sight all the way down.

L J did a good write up (link posted), and Josh Smith makes good quality higher front sights. My own Mosin shot pretty well with no tinkering, I never did try fire it with the as issued iron sights on it tho. I made a replacement set from a 1903a3 front band and base, and cut the stock rear and attached a mini-14 peep

I was just thinking.....a 12" plate at 242yds not knowing where on the plate I was hitting is around 5 moa with iron sights. I need to get on paper and see what it can really do.

Hello,

They all shoot high to some degree without the bayonet affixed.

The first thing a lot of us do is replace the front pin with a higher one. Or some will extend the pin with a slipon sleeve of heat shrink tubing and then shrink it so the top is about 1/16 higher than the stock pin. Otherwise they all shoot high and to one side without the bayonet fixed in place.

Beyond that there are a bunch of websites with hints and tricks. Google with the key words "mosin accurizing" and "mosin bedding" and they'll turn up for you.

I'm going to sight in (100 yards) my mosin on saturday using Privi partisan 148gr SP, i'll see what i can do

My mosin shot between 10 and 12 inches high when I got it, so I extended the front sight post and now its dead on. My brother's, on the other hand, was counterbored and was also dead on elevation-wise. We didn't have to make any changes to the sight to bring his down. Not sure what the difference was.

They are accurate rifles straight out of the box, at least every one I've seen or shot. However, as others have said, Google has plenty of resources on how to accurize them, bed the stock, and all that kind of stuff.
