I hate cleaning. I especially hate cleaning lead contaminated crud from .22 cans. So I’ve been thinking hard for a while about the idea of jacketed subsonic cartridges, which are few and far between, unless you like .300 Whisper.
And then:
Maybe I’ve had too many concussions, but I keep coming to the idea of subsonic 77gr .223, which checks a few blocks for me. I can fire it through any can, because I don’t need to take it apart and clean it. Internet searches show that 5.5-6gr of Trailboss can be stabilized with 1/7 twist, with good margin for error. It should, hypothetically, be pretty quiet with a 5.56 can, or a 7.62 can with a 5.56 endcap, because these tend to be longer and have more internal volume than most rimfire cans. Also, hypothetically, a .22 can suppress better than a .30 with subs. 77gr offers energy advantages over .22lr that the neighborhood raccoon can’t ignore.
How I would go about this:
Green Mountain has a 1:6 twist barrel with rifle gas. I would have ADCO cut that down to 12” and thread it. Straight pull bolt action. I’d try out a few cans to see which one works best on such a low pressure setup, and I’m open to buying a new can just for this.
Has anyone else tried such a project? How does it compare to .22lr subs through a .22 can? Is this whole thing silly?
I just use this ammo in my 5.56 ARs with my normal cans on them:

It is super quiet and cycles. It will not lock back on the last round but i can live with that.
In no way do I make any money from anyone related to the firearms industry.
