    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.

    5.7x28 out of a rifle should be fine in a can that can take 22wmr from a pistol or 22hornet from a long gun.
    Any 556 or 223 can would be overkill.
    Full power 223 is like 25gr to 28gr of boom.
    With subsonic 5.7 you are only talking about 5gr of propellant. Full power is around 7gr.

    An auto loader that shoots Aguila subs sounds tricky.

    But oh... if you could get it to work, wouldn't that be dandy?

    I admit at first a sub-sonic 5.7 sounds like a contradiction, but since you are already set up for 5.7 it sounds like good sense. What is your max practical range with it?

    That Kel Tec .22 mag pistol with something like a 30 round capacity sounds better for your intended purpose, to me, but the FN would definitely be more glamorous.

    Agreed, but I try my best for a quick death.

    The silencerco Spectre is rated for 5.7

    Me, too.

    I am a fan of the Fifty Grain Throat Punch.
    (Or how ever many grains is in a twelve gauge #4:)...)

    But to say a sub-sonic 5.7 is inhumane, is a stretch. Especially if he is moving up from a rimfire pistol.

    I still think it would be cool to have boxes of dynamite left about, but I can’t trust the coyotes to blow themselves up. (And my kiddos not to.) Perhaps relocated Roadrunners could help...:D

    Is a 55 grain vmax designed to expand at those velocities?

    Hornady states 1600fps is the lower limit for explosive expansion.

    Whether that means it will not open at all at sub speed is going to need testing. It could mean they just don’t disintegrate completely, which is what I look for in a varmint bullet.
    I have a feeling they will work even if they act as a FMJ. I haven’t had very many hollow pointed rimfire bullets act as hollow-points and open up anyway.

    Nearly every time I look at a .22 hollowpoint I wonder "Is this really going to work?"

    Neighbor found a dead coyote near his house with several extremely fresh looking small caliber gun shot wounds less than 1/4 mile from where I shot one.
    The suppressed ruger is quite lethal.

    Below around 1,600 to 1,700fps ballistic tip .224 bullets don't really break up much and fmj bullets tend to stay in 1 or 2 pieces.
    So subsonic they might as well be FMJs.

    For hollow point 22lr they do open up when fired at roughly supersonic velocity such as from a rifle, even lead round nose will mushroom out at those speeds.
