You fired 30 rounds of rifled ammo without cleaning it once? How is the accuracy after doing that? I doubt you hurt anything, it will just be a pain to clean is all because of all the lead fouling. Using winchester rifled slugs I can get about 5 shots or so before my barrel fouls out and accuracy goes away. The most shots I have fired without cleaning it when using rifled slugs was 10. I will not do that again, it was not fun cleaning it.

Did you hurt your gun? I highly doubt it. Sabots are pretty new in the scheme of things. People have been shooting lead slugs out of rifled barrels for quite some time. It just requires more work is all. No different than shooting buffalo bullets out of a muzzle loader, or non jacketed bullets out of a pistol.

Get some good brushes and a decent lead remover and get to work. Be prepared to make a mess as well. It will take several passes and a fair amount of time to get it completely clean would be my guess. Just take your time and do it right.

That is one of the upsides to using sabots. They leave the barrel very clean when your done shooting.
