Larry - How about a picture of the breech-end of your gun. I'd like to see what the extractor and rim look like.

Ok, there are some good ideas here, but I'll have to do the measuring and pictures when I get back from a business trip next weekend.

Thanks again guys for all of your thoughts.

Larry

Larry,

Just some additional ramblings about your chambers.

I've given it some more thought and have come up with some more possibilities for your chamber situation. When you measure your chambers be sure to measure the chamber length. It's possible that someone wanted to legthen the chambers to the more modern 10ga loads. Here's the senario: the owner takes the gun down to the local gunsmith and asks to have the chambers lengthend. The smith doesn't have a ten gauge piloted reamer because he doesn't have a call to do many 10ga guns. So he takes a dull non-piloted adjustable reamer and goes for it. Now he has chatter marks in the original chambers and then takes a brake style hone to them too smooth out the chambers and the end result is over sized chambers and possibly an unsafe gun. The owner then realizes he has a ruined expensive gun and puts the gun up for sale and sends it down the road.

My suggestion is to measure the chambers and then contact a top shelf barrel man to get his opinion based on your findings. What ever you do; Please don't shoot this gun again until this issue has been resolved. The highest pressures are generated in the chamber area and the last thing you want is for your gun to blow-up in your hands & face because someone altered the chambers.
