This should help.... Nice and big for bad eyes too!

Thanks for posting this. I remember seeing this article in a 1975 American Rifleman and, as a technical writer myself, am still impressed with Ludwig Olson's economical, precise and well-crafted prose style. I myself have 5 or 6 Model 10s and really admire them for the beautiful design that John Pedersen came up with. The take-down diagrams in this article are very useful and I've used them many times. This is a very easy gun to dismantle, although I must say removing the breechbolt from the receiver is easier than replacing it! But in messing around with it (making sure it's well oiled) you get the hang of it.

Another thing I've learned with the 10 is make sure you remove the barrel group from the rest of the gun before you swab the barrel because it's really easy to bend the extractor spring out of shape. You can also go to Home Depot and find a replacement stock bolt. Just take in your guard (part 23 below) and find a thread that matches. Numrich in NY state used to be a major purveyor of Model 10 parts, although I haven't needed to use them in years so I don't know if they're still around.

I think the barrel adjusting bushing is a real weak link in an otherwise great design. Now that I think of it, the tang screw arrangement is pretty weak too, needing constant tightening. If you are a machinist or know one, it might help make the tang structure more rigid by countersinking another screw closer to the butt end of the tang. That might help it from wobbling laterally from side to side. I have never tried this, but it seems like it might work. Enjoy your 10; they're good shooters and mighty fun on the trap range.
