Did I screw up the bore?

[gene pool]

Gentlemen,
Last night I noticed a lot of copper fowling in my .243 hunting rifle. So I got out the bottle of Shooter's Choice Copper Removal and swabbed the bore. It says to leave it in the bore no more than 5-10 minutes, however I got distracted (better known as a senior moment) and left it in for 23 minutes.

My question is, did I screw up the bore? If so, is there anything I can do to recover?

Thank you in advance for your comments.

I would say- NO. I leave 50bmg/copper killer in my barrels over nite.tThe only cleaner I know of that you shouldn't leave in more than 15 mins is Sweet's.

I would say no as well.

Na....How well did it work?

The main reason they tell you that is ammonia attracts moisture. The ammonia itself wont corrode steel unless highly concentrated.

Thanks gentlemen. I have not had a chance to try the rifle yet so maybe I am OK. The patches came out green with a little gray. I wiped the bore thoroughly and applied oil.

Thank you for your comments.
