If you can get a brush down the barrel, I would think a patch wouldn't be a problem. Can you look down the barrel to see if it's obstructed? Is the rod bent, or the jag too big? I can't think of any other possibilities.

Maybe the bolt or the area around the bolt is still loaded up with old grease/dirt/gunk/whatever. Can you get the bolt out?

I quickly searched on the internet but I didn't find a link to a manual or any instructions on how to disassemble the bolt. Got any friends who are gunsmiths?

The barrel is clear. It's actually pretty shinny now. And the rod was the same for brush and patch. That's what confuses me. I'll probably have to invest in another Otis kit.

I got the bolt out and there a ton of crub on it. I got a good deal off with a few brushes, I'm sure there is still more inside. And I couldn't find info for taking the bolt apart, either. No one seems to know how to do it.

Once my Sig gets her date with the gunsmith I'll probably bring the rifle along, too, for good measure.

Contact the technical department @ brownell's in montezuma, iowa. They can instruct you how to properly disassemble the bolt for internal cleaning. The only bolts i have experience & the tools to do it are the howa 1500 & the rem model 721 / 700 series.

SL is pretty clever. After over 3 years, I'm pretty sure she's got it figured out.
