That's what I want to do also. I have posted a couple of questions on silencertalk those guys are really helpful! I have also read through your post on your 22 can. I look forward to seeing your new toy.
I'm in the same boat. I've been doing some design research here and there and may start getting more serious into it. I might have to pick your brain, bkoenig, but unfortunately my access to the machine shop at my work is strictly limited to... well... not this
At first I started looking at designing a can for two of my pistols and realized quickly that I would need a booster, seriously complicating things. Then I got to thinking about a 556 for my current ARs or one for an undecided 308 bolt that is in my future.
Congrats on your paperwork, btw! Happy Day!!!
