Don't Do THIS

[JCHannum]

The enemy of twist barrels was rust, not pressure. If the gun has been cleaned and maintained properly, it could be OK to use with low pressure loads.

You might ask or poke around on the double gunshop forum, there is a lot of good information and some very knowledgeable contributors there. The subject comes up frequently in one form or another.

In the 1960s I had a friend that lost his left hand to a damascus barreled double. It was rusted between the ribs and could not be seen inside or outside the barrel. My advice do not fire with any load.

If you really want to fire the double, there is one safe way assuming the action is sound. Use gauge reducing liners, they will give the strength of modern steel barrels and keep the gun original. You could make your own from 20 gauge barrels if you have a suitable lathe.

Liners are a really good Idea.
Thanks for the suggestion.
Does anyone know who makes 12 to 20 liners?
I didn't mean to hijack the OP's thread but some how my post ended up here.
Sorry bout that----

I did not look through their other styles. I have read that Briley makes a top notch product but have never seen one in the flesh. I think at one time Savage might have had tubes available but do not know about any other vendors. Read the Briley sight, use their descriptions for a google search.

These look like just what you get in the deprimer catchall. They don't look to be symptomatic of anything. If these were on the bench after you fired them, then yes, too much pressure. If these are just what you got depriming the cases, then no big deal, unless you have loose primers when reloading the brass.
