Part 2: Installing the Upgrades (link)

This build is in a deer & feral hog hunting configuration for use in Central NC… so most shots 200 yards or less and from a tree stand or ground blind. We will shorten the barrel to about 20″ to make it easier to maneuver when deer hunting in the brush. Although, if pursuing feral hogs on foot I’ll likely use the WMD Guns WMD-10, AR-10. 🙂

The donor Mosin Nagant is just a run of the mill, arsenal refinished 1943 Izhevsk Mosin Nagant 91/30 picked up at the local big box store for $185 out the door. My research indicates that of the 37 MILLION+ Mosins made, this is one of the most bland and uninteresting models available… if not THE least desirable Mosin in the eyes of collectors.

The Plan:

  • Start with a donor Mosin Nagant rifle, the 1943 Izhevsk Mosin Nagant 91/30 noted above.

How did the Mosin Nagant Rifle perform before upgrades?

Very poorly.
For a 70+ year old military surplus rifle that was made at the height of Russia’s wartime production, when production numbers were more important than quality, I suppose it wasn’t that bad. By modern standards it wasn’t very good. At 85 yards our old 1943 Izhevsk Mosin Nagant 91/30 only managed to put 2 of 3 shots on our EZ2C bullseye target. The picture shows the target which has a one inch grid pattern. The 3rd shot is near the top left corner of the image along the left edge… on the wood about an inch from the paper. The group measured nearly 9 inches shooting a mix of old milsurp and PPU rounds. Shooting was done from the Hyskore Dual Damper shooting rest, which should have helped a lot to tighten up the groups, but suffered from a the shooting bench being less than totally stable due to uneven ground and having to boost it up a little to shoot over a fence.

Mosin upgrade first shots

The first 3 shot group only put 2 shots on paper

We changed to a taller shooting bench to see over the fence easier and switched to only shooting Prvi Partizan PPU 182 gr FMJ BT. This shrunk our best group to about 4 inches. Not good, but better than the first attempt.
