he's right.
I gotta go with madmo44mag on this one. C & R is addictive. I have a 91/30 Tula 1943. I would suggest that you field strip the gun. There will more than likely be cosmoline in every nook and cranny possible. Clean it well. After cleaning, place barrel in stock and tighten action screws to 50 inch pounds. Use a dollar bill and see if the stock hits the barrel anywhere. These are known for stock warpage causing pressure points where they shouldn't be. Carefully sand the area hitting the barrel until clear. Also, these do not seem to like a floating barrel. "Cork" it using cork gasket material or bicycle inertube strip about 1/2" wide, placed in the front of the stock's barred channel, just behind the nose cap. This puts a slight upward pressure on the barrel and usually shirinks group size considerably. Keep an eye on those action screws too, as they like to loosen up. You can also tweak the torque on these to see where your gun likes them at. These can be finicky but accurate if you take the time to love them. Have fun!!!
