No Jager, not that bad, even with surplus ammo.
I just participated in a postal match. While results are not in yet, I do believe I did well.
I have a Mosin M44 carbine made in 1944, and shot 50 yards using Czech military surplus made in, oh, '62 or so. We used an SR-1 target. The X-ring is an inch across, and I plunked three of five rounds into that circle.
This was with stock sights.
If I had been shooting heavy commercial, I would have had all five shots in the X-ring.
You will not see the full accuracy potential of your rifle with stock sights and surplus ammo. That ammo is fun to plink with and the sights cover maybe 4" at 50 yards.
This is likely where people get the inaccuracy myth. You do realize the .30-'06 and the .30-30 are inaccurate as well, right?
I did do quite a bit of work on the insides of my barrel to make it shoot like this. All I did was I cleaned out the copper layer, then the grime layer, then a thin rust layer.
The M44 is considered a carbine, and inaccurate by the way.
My next project will be a Mosin-Nagant 91/30 (the long rifle), cleaned up as I did the M44, with a low power, forward-mounted 'scope on it. This will be a dedicated sharpshooter and will be used to take coyote at long range.
But think about it: If 3/5 surplus rounds stayed under an inch at 50 yards for me, with the flyers being my fault, and also due to the course sights, then my carbine should theoretically do under 2" at 100 yards if I were to 'scope it and bench it at that distance.
The sniper models did 1.5" on the outside, and were just stock rifles pulled off the assembly line due to accuracy during testing. They were outfitted with a 'scope and a bent bolt handle, and called a "sniper rifle."
Finnish snipers didn't even use a 'scope. If you feel like drilling and tapping for a 'scope, find a Finnish M/N. They were a bit anal about accuracy.
This is a 50yd 2" group fired by me, standing, with a field expedient rest. Discounting the flyer and shots fired at the wrong elevation, I managed what I feel is good accuracy. 
Again, discounting the flyer, a good group. Remember that the front sight appeared larger than this group at distance, and I did a lot of guesswork to make them punch the paper where they did.
I say get one, learn it, then spend some time fixing it up.

Then mounting a scope on it and, refinishing and glass bedding the stock and working over the trigger. What I would like to know is what kind of accuracy am I going to get? Ive read some places they get 5 inch groups and other places there getting 1 inch groups. Tell me what you guys think.
