As far as I know there is no legal way to NOT have to actually face-to-face transfer the can to you, unless you are an FFL- a 'normal' FFL can receive transfer of a can to himself via mail. So basically unless you're an FFL, Bob, you're going to have to incorporate your actual transfer into your annual trek to Los Anchorage. Which isn't that big of a deal since the transfer to your dealer and clearance of the paperwork is going to take forever anyway. You got to do it for rifles, you got to 4473 the can too. By the way, who did you get to sign off your form4? I've often thought that legally a VPSO could sign, and I know a fur & feathers officer can too.
As for your dealer/can, I've heard of Bob and I think he's alright. Jet- is that his brand? Is it a local manufacturer? Never heard of it. I've got 6 cans from 4 manufacturers and another 3 or 4 on the way and what I've learned is- you get what you pay for, and what you want from a can is a subjectively good sound and as important if not moreso- PRODUCT SUPPORT. You will never sell the can- the tax stamp to sell it again makes it cost prohibitive. So either listen to the damn thing before you buy it or go into the deal knowing there is a possibility that it will suck.
As to the particular can you mention, ask your dealer and/or the manufacturer if it would be possible to shoot .204, .223, .260, 6.5, and 6.8 through it. I don't know the pressure of the 6.8 but my gut tells me it's fairly low so your manufacturer might be building the can down for this. While the hole will take a .22 calibre bullet, it might not take the pressure of a .223 or .204. Discuss the possibilities of oddball calibres with your manufacturer. I called Gemtech and spoke with both Doc Dater as well as Kel about using my M-496D on my .17 Remington AR upper and others- they got really squeamish about using ANYTHING but 5.56, as that can is specifically built around a standard 5.56 load. As such it works absolutely amazing- for what its built for. If your can is going to be an all around can I'd ask about being able to use it on the smaller rounds too, if I was you. To me the actual can ID seems like it'd be 'good enough' for you to appreciate its effects on the 223 and 204. The older American Manufacturer .30 can actually was damn good sounding on a 223 M16, as good as a 30 upper.
As for hunting with the can you can legally use a suppressor for trapping so you're cool with it. Try it out, you'll be surprised as to its effects on the critters with your standard supersonic loads- the can has an effect on the perceived location of the shooter so half the time the bastards will either come running right after you or run at a right angle. It certainly makes shit interesting.
DO NOT USE ANY SUBSONIC LOADS THROUGH A STANDARD TWIST BARREL AND NOT EXPECT YOUR CAN TO HAVE A TOTAL AND COMPLETE COMEAPART.
