91/30 accuracy (lack there of)

So I get this 1943 dated M91/30 in pretty much MINT conditon(probably refurbed)...perfect wood/perfect metal/gleaming bore

It shoots 12-15" groups.

really....this is with the yellow tipped Hungarian heavy ball.

What does one look for when a excellent condition gun shoots like a slingshot?
How can this thing be 'accurized' without screwing around with bedding or crap like that?

This is pretty important as I intended to mount a '41 dated PU scope on this thing and make myself a 'Zaitsev' rifle. But if it wont shoot it aint gonna happen

Barring all that....anyone want to trade a excellent 91/30 for one that shoots?

I have had the same experience with my 91/30 Mosin just a few weeks ago. The rifle was absolutely mint without a mark on it. A rebuild, but very nice looking rebuild. It shot 14-20 inch groups at 100 yards, regardless of ammo. I took it in to the gunsmith and had it re-crowned for 40 bucks and now it shoots 3 inch groups at 100 yards. Many times the rebuild process was incomplete or re-crowning was improperly done as with mine.

For those that don't understand the importance of a proper crown: if the bullet lets go on one side before the other, the gas pressure releases and gives the bullet a shove to the side. The bullet straightens out as it flies, but it gives you less than adequate grouping. Most crown problems are caused by improper use of a muzzle protector during muzzle end cleaning. Some re-crowning has been poorly done by hand as well. Lots of milsurp rifles have this problem. The SKS is a regular example of this. A Mosin should shoot and hit at a paper plate for as long as you can see it.
 
Friend and myself played with several of these for a number of years, actually got some very decent iron-sight shooting out of a couple.

His trick was to 'take care of' that long, slender fore-end. You know the one: it wags like a pup's tail ahead of the main stock of the rifle. Likely they were fine when they were made; the wood was made that way to protect the shooter's hands and to provide a relatively light control on the muzzle. The problem is that Time is NOT on our side and 70 or 90 or 100 years is enough for even the best-cured wood to warp..... and nearly all MNs were built during wartime, anyway.

So we glassbedded the frame solid, so as to keep the rifle and the stock in the same place at the same time (we had discovered that 'more or less' just doesn't cut it with the MN). The slender fore-end we took care of with a 9-inch length of 1/4-inch steel rod which was buried in the woodwork (after routing out the channel very carefully) for about 4 inches at the belly of the stock, the remainder under that floppy fore-end so as to stiffen it. When everything was good and solid, we installed a half-inch pressure point right at the front of the fore-end. Rifle shot very nicely out to 400.

My friend then determined that he wanted it better yet, so he glassed in the cleaning-rod (!) and shot it like that.

For the next 4 years, every trip to the range the first 3 rounds were out of the old MN, shooting at a 4x6 piece of tarpaper at 325 yards chained, and that was Summer or Winter, 90 above or 30 below. They were ALL on it.

Gavin Tait regarded the test a success and the $169 expended on the rifle (with all equipment) as money well invested. I just learned a lot.

BTW, we were shooting WITHOUT the bayonet attached. The Russians issued no scabbards for their bayonets; they were kept fixed at all times. It looked great in a parade, but I think that part of this would have been to ensure sufficient pressure on the relatively-flimsy stock at the muzzle.

Hope this helps.
