Seems as though some here don't own any live stock or have driven up on the remains of a chicken massacre the next day and had to kill sixty of them that weren't dead yet. And still not get to eat any of them. One hundred and ten dead just to take and eat two. That doesn't sound like a balanced nature thing to me. Acme hasn't done enough to thin coyote numbers. My kids need to eat too. Upon relating your ideas to me, @748, I have given up on my plan of a rimfire upper set up for the Aguila SuperSubSonics. This seems a much preferable option. Mostly the ammunition customization, as putting in more or less powder is easier than tuning springs and conversion adapters and finding portless barrels in the wanted twist. I know very little about the suppressor side of it. I suppose a rimfire can would burst. Would one that works for Two Twenty Three work the same? Good luck with the hunt.
