The Moisin Nagant Model 91's are what they are, ugly, cheap but functional. We should all have one, and a spam can of ammo. JIC.
Why they shoot high, and how to correct it. Actually floating the barrel, and tuning the bolt.
Seriously...

Here's a great set of "realistic" MN reviews, and tweaks. A funny read to those that own one, and an inspiration to get one, if you don't.

The Mosin Nagant 91/30 is a blunderbuss with a bad attitude, a fierce weapon of war from the tip of its pig-sticker bayonet to its skull-cracking iron butt plate. The original 91 was introduced in 1892, improved in 1930, and remained Russia’s top infantry rifle until 1945. Like the Ivans and Ivanettes who carried this beast through seven wars, the Nagant rifle packs a punch. It’s big, robust, heavy, loud, rude, sometimes crude, iron-balls tough, ugly in a beautiful way, cheap, historic and a whole lot of fun if you go easy on the vodka. Whoa. I just kinda described myself if I drop the historic thing and add more vodka . . .
Some owners have lugged this heavyweight rifle to the range, only to discover that their 91/30 couldn’t put a round in a rain barrel at 100 feet. That’s when they start to tear the gun apart or beat it like a redheaded mule. Don’t! With just a little effort, it’s possible to wring out some extra performance from a 91/30 and make it a nice shooter . . .The process starts with field stripping, which is about as intellectually and physically challenging as removing the cap from a tube of toothpaste.
MN rifles that were battle-zeroed at 300 meters (about 328 yards) took into account the sizeable bullet drop from muzzle to target at that distance. At 100 yards, though, the bullet is still rising from the muzzle, impacting high by an inch or two. Add that 2 inch rise to the 8 to 12 inches of drop already built into the 300-yard zero, and the MN hits not just high at 100 yards, but embarrassingly high. Like a foot or more high. Like Lindsay Lohan high. I’m talking high.

Love those cheap, FUGLY, rifles.....
