Just replaced the stock on my 1943 Izhevsk 91/30 with the ATI stock. Very nice looking, mine was definitely not one of the ones that would drop right in. I had to sand down a fair bit of plastic so the ejector would function.

The stock is also very tight all the way up the forearm along the barrel. I had to use some force to squeeze the barrel into the recess. I am wondering if I should attempt to partially float the barrel to the front of the stock and bed the very end giving the barrel some upwards pressure? One of the things that frustrates me about the online reviews of the ATI stock and people who floated its barrel is they don't talk about how it grouped before and how it grouped after! I don't care how the thing looks, I care about how it shoots.

My rifle has a pretty good bore and crown, I had it out with the new stock the other night and the results were so so.. about 5" groups at 60 yards but light conditions were poor and I did not have a proper rest.

I don't want to ruin a stock I just paid $80 for and make the rifle shoot worse. Should I leave the stock tightly gripping the barrel or should I sand out the channel?


Thanks,


F. Steele
 
How does your Mosin shoot in its standard stock?

The first thing I would do is take my Mosin out with quality ammo or handloads and see what it truly is capable of in its original form.
If you can group less than 6 inches at 100 meters with irons then your rifle is doing pretty much all that was ever asked of it.
That is right out of the translated Mosin Nagant rifle manual.

You need a solid reference to compare it to before you start sanding down the channel of the ATI.

If the rifle shoots far worse than before in the new ATI stock, I would try and replicate the original configuration by sanding the channel down ie. The barrel is floated from the receiver up until about 2-3 inches behind the tip of the stock.
