Does Titanium Expand? (as compared to other metals)

My friend claims that after he has cleaned his steel revolver, that the next day, he needs to clean it agian. His theory is that after a night, the metal in his gun contracts and when he runs a clean patch through it, it comes out dirty when he had cleaned the gun the day before. Does anybody else here expirance this and if so, has this ever happened with a titanium gun?
 
What's he doing? Baking his steel revolvers in a 400 degree oven for an hour before he cleans them the first time? If you clean your guns correctly the first time, hopefully the same day you shoot them, you don't need to clean them again the next day.

U.F.O.
 
Probably didn't get it all the way clean and the gun oil dissolved a little more crud out of the bore overnight.
 
Fouling CAN work it's way out of the pores of the bore.

When cleaning the old corrosive ammo used in service rifles, you would clean the rifle thoroughly, then clean it again for two succeeding days to remove the corrosive fouling that leeched out overnight.

This is quite a bit different than cleaning the bore, then having carbon or bullet fouling "reappear".

In his case, I suspect he's missing some crud.

Also, remember that running a patch down even a super clean bore can produce a patch with dark stains on it.
This is metal stains from the patch rubbing, not fouling.
 
Titanium expands a bit more than steel, for a given temperature. But Ti revolvers have steel barrels.


I agree with John about the dirt.
 
It has been my experiance that running a patch through the barrel of any of my guns the next day will remove a bit of dirt. I always thought it was just the little bit of solvent and oil working a little more dirt out.
