So I finally got around to shooting some Privi Partizan ammo out of my Mosin. And I gotta tell you that I'm pretty impressed with the results.

Oh, before I go further I also have to add that I broke down and bought some targets to aim at which are "old guy eyes" friendly. I picked up some 8 inch and 12 inch Shoot NC targets that I stuck onto big sheets of white paper which were then stuck on the stands. The hard contrast of the solid black on white is the first time I can say that I've been able to truly see any target with plain iron sights well enough to aim with confidence. The gain in my sight picture accuracy is likely half the reason for my better shooting.

Previously with mil surp ammo and a 12 red painted pizza plate I was getting 8 to 10 inch groups at 100 yards with lots of flyers as well. This being with the rifle shot from a rested sitting position. With the better sight picture and PP ammo this shrunk to around 3 inches for groups shot by myself and a shooting buddy.

At 200 it took a few rounds to get the right elevation change but we had enough to shoot a few for grouping at the end of the box. By this time my shoulder was getting sore so my shots were out around 8'ish inches. But he was keeping the last 6 or so rounds all within a 5 to 6 inch size group aside from a flyer.

These flyers were something else. I'd expected an improvement from the factory ammo and I got it for the most part. But out of the box of 20 we had 3 rounds which were not in any way at all close. Like I mean the shot went from on the black for shots each side of the flyer and the flyer was a good 12 to 14 inches away from center at 100 yards. I know it doesn't take much of a twitch to get a flyer but I didn't feel the gun "pull" in my hold at all. SO I'm wondering at the consistency of even PP ammo.

The other good news is that this was a warmup for reloading my own 7.62x54R. Recently I managed to put together the bullets, brass and dies needed to reload my own.

With my own loads and with some playing around with testing and "corking" the barrel I'm hoping to shrink the groups down even further. I do know that I'm feeling a lot more happy about shooting my Mosin now. And I'm likely going to shoot less and less of the milsurp ammo as a result. In fact out of the two SPAM cans I got I'll likely sell one off since I can see getting to where I just don't shoot any milsurp ammo at all.
 
Prvi Partizan makes excellent ammo. Mosins can be accurized. Have you slugged the bore? If you can, this may help determine desired bullet diameter for reloading. Buckshot balls are good for this. Find one that is slightly oversized and some wooden dowels to tap it down, http://www.youtube.com/watch?v=ErFaJlUVs1Y.

Second of all, you can bed the action with glass bedding... iraqveteran8888 http://www.youtube.com/watch?v=VFeDm7DMgzo&list=PLoagig7ANyXONhKngPiMykylF3sawzUx6just posted a video on this very subject on youtube. It is an excllen video.

Third, see if you can smooth out your trigger. Again, iraqveteran8888 did a video on this last week, http://www.youtube.com/watch?v=7RlsxqR_keM&list=PLoagig7ANyXONhKngPiMykylF3sawzUx6

It's super easy to do. Fourthly, check the crown. I just finished the crown on my mosin. If the gases don't come out evenly out of the muzzle this will totally throw off your accuracy. I can guide you if you're interested. You need a variable speed drill, use ultra low speed for this, in other words, do not be in a rush. You need a 1/4 brass machine head screw (flat screw driver slot) and some valve grinding compound. A scrubbie pad (scotchbrite pad) to smooth it all out and some ultra fine grit sand paper to wet sand with oil to polish it up.

good luck!
 
Sam', I'll have to slug the bore as you suggested. And good call on that. It had skipped my mind to do so. The rest of the stuff is already on the "To Do" list.

Trigger smoothing and length of throw was done already. I posted a thread some time back about using some of the plumbing strap soft steel as a shim for the sear/trigger spring and I've drilled and tapped under the bolt for the set screw mod to reduce the trigger creep.

The primer strikes are DARN strong so I'm also going to try a mainspring swap to reduce the force and thus further lighten up the trigger as well.

My machine shop should be back up and running in a couple of more months. Once that's done I'm going to make up a muzzle crowning tool to lap in the crowns that is guided by a pilot that is centered and locked within the last few inches of the bore. That way I don't just shape a crisp edge but I can correct any slight face misalignment at the same time. It'll be a big step up from the screw and lapping compound.
 
PRVI is superior quality commercial ammunition than American made cartridges IMO. Both PRVI and S&B have good quality brass for reloading. When it comes to reloading Mosins, EVERYTHING I reload is a .312 bullet and shoots better.

You're definitely better equipped to accurize your rifle than I am!! You have access to a machine shop, AWESOME! Let me know how this turns out for you! cheers
 
It's good to see that you folks like the Privi brass so much. It happens to be the brass I got from Budget Reloading and the same stuff I got two boxes of loads for. So I've got 140 casings to work with now.
 
Prvi is the best brass made for the 3 big calibers from WW2 - 303, 8mm, and 762x54r. The loaded ammo is great too, no nervous downloading - you get 'real' service rifle velocities and pressures and most of the time it actually costs less than the watered down US stuff.
 
I have about 1300 pieces of 7.62x54r, evenly divided between privi and igman. I have lost count of the times they have been reloaded and used in 80 different rifles. Thus far, my failure rate has been less than 1%. Good brass indeed! My 8mm cases have been reloaded more than ten times, for 16 different riles and I am just starting to think about scraping that lot.
 
Prvi.....loaded ammo is great too, no nervous downloading - you get 'real' service rifle velocities and pressures......

After shooting the half box of Privi ammo my poor shocky shoulder would agree.... :D

I've picked up some cheapie flip flops from Walmart and have some leather kicking around. I'll be making up a slip on recoil pad SOON! ! ! ! It's either that or find one of the old surplus Russian army wool great coats for padding. But with Summer coming up that might get a trifle warm.... :D
