Vinegar and peroxide are useful for lead-fouled barrels. I first found out about it at Homemade Firearm Related Products
I've tried it in a Cugir trainer .22 and it works. Messy, but gets the lead out.
I have a daughter. I tell her, "911 is what you dial after you're raped. 1911 is what you should have before they try."
You can put any can that is made for a larger bullet on a smaller one...like a .308 can on a .223 but not the other way around. I just don't know how the sound would work...I'm from NY ;-)
Good luck on the from 1 tax stamp. I've been waiting over 4 months for mine for my .300 whisper project. Once I get this one, I'm thinking I'll submit 2 more form 1's. One for another can and one for a SBR. That'll give me something to wait on for the rest of the year!!!!
Good luck with the can.
Good information on the cleaning aspects.

Be like an old dog!!!! If you can't eat it or screw it, just piss on it and walk away!!!!
Older designs relied on the bullet to "plug" the baffle by keeping the hole pretty close to bullet diameter. This forced the gas to expand into the hollow space between them during the time the bullet was passing through the baffle. More modern designs use specially designed baffles with passages in them that use the high pressure gas against itself, essentially sideways jets hitting the stream of exiting gases to break them up. These typically have much larger holes in them over bullet diameter. One advantage is any minor misalignment from a loose suppressor or improper threading will not cause baffle strikes. Some .223 baffles have 3/8 to 1/2 inch holes in them.
