    shot mostly wolf and surplus ammo thru mine but did get around to doing some handloads with some S&B brass. beating a dead horse here but 1.4" group is acceptable for these relics I think. They're just plain fun to shoot!

    I have a 91/30 rifle I paid $70 for, cut the stock down to a 'sporter' and added a bipod; decent groups, haven't shot it in a while though, don't remember exact accuracy. Also got a 44 carbine with bayonette, not as accurate but still OK.

    did manage to find some stripper clips at a gunshow too...

    bought a 'sniper scope' bolt from Numrich but it was just a bent bolt, still won't work with a scope. I had aspirations to scope the 91/30 but think I will just leave it as is. Trigger is terrible but ya know... $70 and free carbine = 2 MN's, I can't complain!

    IME, the Mosins I've shot are more accurate with

    cool barrels, and name brand, boxer primed, reloadable ammo.

    I'm currently saving all my used boxer rounds in the original boxes,

    in the hopes of finding a good "MOA reload" eventually.

    My 1925 Izzy "transition" (got the 91/30 front sights, stock, and

    barrel bands at either 1930, or before postwar storage) has a god-awful,

    loosey-goosey, long trigger pull, but my two M44s have two of the best

    triggers I've ever shot, on anything.

    I got a bull pup stock from cbrps, and it looks pretty good as you can see in the pic. It's the Cossack ES in white. A bit pricey, but I was able to mount a bushnell scope on it and it was getting decent accuracy for a rifle made in 1934, and that's with mil surp rounds.

    If your Mosin is not accurate, heck, just throw it away and buy another one:eek:

    I know this may be an old Post, and I am an extremely new member, but... I do have allot of experience with the Mosin Nagant. Over the years I have used this platform for some really reliable custom builds for myself and my customers. Now what I am going to say will not be popular I am sure ( at least to the purest out there) But there are several things you can do to produce a really excellent shooter.

    1. Polish the bolt in every nook an cranny and reapply grease. There are some really great tutorials on line to teach you how to do this.

    2. Shorten the barrel. I have found that if the barrel is taken back to between 18 - 22 inches, your groupings will improve greatly.

    3. Replace the stock and or bed it. This is one of the easiest things you can do to this rifle.

    4. Replace that god awful trigger group. There are several ways to do this easiest way is to drop in a Timney trigger, this also gives you an easier to use safety. If you dont want to spend the additional 89.00 usd you can always attempt to turn the factory trigger into a two stage trigger using a washer and a spring. This is an easy process however you will need to inspect your firearm and do a little research on how to do it. I personally have done this on a few of my pieces , love it but I personally prefer using a new trigger system.

    5. (optional) replace the rear sight with an optic. someone in a previous post mentioned the rear sights may drift and this is true, for the most part the Mosins on the market today are refurbished World War Two rifles, they have seen allot of use and wear and then sat around for the last 40+ years. There are several ways to mount a optic to the rifle. the Most common and successful is the Rock Solid Mount. Me personally I turn my bolt into a Bent Bolt and tap out a spot for mounts.

    Now allot of people will call you crazy for taking a surplus $150.00 rifle and putting this much money into it, and thats fine we all have our opinions. But I will tell you this my current project has turned that surplus rifle into a $950.00 nail driver. And if you look at the big picture 880 rds at 164.00 usd add that up over the lifetime of the rifle and it quickly becomes the cheapest shooter you will own despite almost dropping a grand into it. Also don't feel guilty about modernizing this old rifle, this was one of the most produced rifles in the world, still in use in Finland today, that there is no risk of you destroying a truly rare rifle. If you do happen to get a hold of one that was made prior to 1935 or a sniper version made prior to 1943 then do not modify it. Other than that...go to town, your little project wont put a dent in the Mosin Nagant arsenal.
