What to look for when inspecting older shotguns?

[Preacherman]

Dave McCracken's post in this thread (http://www.thehighroad.org/showthread.php?t=178961) got me thinking. He made a number of valuable points there in connection with older 870's, but there must be more things than those he mentioned, and I'm sure other models (Mossbergs, Winchesters, Ithacas, etc.) have their own pet problems that might be found on inspection.

So, how about using this thread to post specific info about what to look for when inspecting a shotgun, along with details of how to fix it, and the approximate costs involved? Also, would a gunsmith's services (or the factory's) be required for the "fix", or is it something that one can handle on one's own?

Perhaps Dave could expand on his previously-mentioned 870 tips, and other users who are experts on other makes and models of shotguns could post their tips as well.

OK, since you asked.....

A few things not model specific....

Check the ends of the wood, both stock and forearm. Look for hairline cracks, oil soaked wood, and sundry wear on checkered areas. Oil soaked wood goes soft, and if it was owned by a dolt there may be other probs. Worn checkering may indicate lots of wear, or that it's a former favorite loved and used for decades.

Blue missing at the balance point usually means it was carried lots. Maybe shot little, but the breech face and/or bolt face are better indicators.

On US made guns, an odd barrel length usually means it was shortened. The choke markings would thus be invalid. A tape measure is a good thing to have with you.

Measure the LOP also. This is the most common alteration done.

Check the muzzle for any signs of alteration and/or ovaling.

Check the whole barrel for bulges and dents, and a ring bulge right behind the choke often means it had steel shot through itwhile not designed for such. Other things will ring a barrel,usually only a Full choke is affected.

Look down the bore. See if the shiny circles line up nicely. One can detect a crooked barrel this way.

BTW, crooked barrels are quite common.

"Ring" the barrel. Hang it by the lug or retaining ring and tap it with your finger or a pencil. The sound should be a clear, ringing tone. Buzzes or a dead thud mean big time probs, no matter how enticing the piece may be otherwise.

Check the fit of pad or plate to the stock. Lots of these get redone, and oft the replacement is just a little off. This affects cosmetics only.

On break actions, remove the forearm and see if there's play between the barrels and receiver. Shake it a little.

HTH.....

Hi Standards- look at the locking recess in the top of the receiver (viewable through the ejection port) for signs of the metal becoming deformed at the rear edge of the recess.
