Daven: If you decide to by a used TC (or investarms), before you go shopping, buy yourself a .45 and a .50 brass cleaning jag. If you buy them with #10-32 threads, they will fit the TC ramrod. These will turn out to be cheap insurance (a few bucks apiece). Also, get some cleaning patches for a .45 caliber gun. Put a few drops of oil on a few of them and put them into a plastic bag so you can take them with you.
When you find a likely gun, put the correct jag on the ram rod (or take a cleaning rod with you) and place the patch on the muzzle.
Slowly shove the patched jag down the barrel.
It should be moderatly hard to push all the way to the bottom.
If, somewhere along its journey to the bottom of the barrel it suddenly becomes easy to push, beware! If its resistance returns to about the same as it was further up the barrel, retract the ramrod and patched jag, hand the rifle back to the seller and say in a loud clear voice NO THANKS!
Someone has fired the gun without seating the ball and "ringed" the barrel.
Although it may not be dangerous to shoot, it will never shoot accuratly and there is no way to fix it without buying and fitting a new barrel.
I don't believe TC will honor their guarentee in this case either because the gun has been mistreated.
If the gun passes the above jag/patch test, when you retreve the patch check it for rust.
If rust is present, get a strong light and use it to look as far down the barrel as possible.
If the rifleing looks smooth and without pits, the rust is probably just on the surface.
If the rifleing looks pitted, it's your choice.
Light pitting won't hurt accuracy. Deep pitting will tear the patches and really screw up the guns accuracy.
Bottom line? I would go with a new Cabelas so there is no chanch of gettin tooken. :hmm:
