I was cleaning my .223 and accidentally ran a .243 brass bristle brush through the bore. I only ran it through once from the chamber to the muzzle then unscrewed it. I was a tight fit but it did not seem too hard. I had Hoppes #9 on it. I accidentally used the wrong one, think it is ok? Thanks

No harm done, so you can sleep easy tonite!

Thanks, i was sweating it!

Fret not. I do it routinely.

Redial

I routinely us 9mm brush on my 8mm Mausers...to cheap to buy an 8mm, when thw 9mm works just fine!
