interesting what you can kill w a subsonic .22 lr placed well ...
Subs don't deform much, placement is everything. When this learning exercise began I found that up to around 80-100 pounds or so that CB shorts would exit broadside shots in the neck, to include mangling the spinal cord. Pop'n flop every time. Standard HP shorts would shatter on the spine but still do the job. No exit.
The large pig above, bullet recovered about 6" behind the skull in neck muscle:
From the rear looking forward:
I also found that the CBs were prone to straighter path wound channels than LR ammo....substantially. Typical range on the shots taken is around 20 yards, longest was measured at 38 yards as I recall.
Have yet to use HV RF ammo on hogs.
Interesting topic, wish I found it earlier.
As far as varmints are concerned, I have put to the ground everything from coyotes on down to squirrels with both 22lr and the 22 mag... Some bang flops, some arguments, spinners and short death runs.... Skunks are incredibly durable, more so than coyotes I believe.
There is a few houndsmen here that are passionate cat hunters, as in bobcat and mountain lion, around here that use the 22 mag to turn off tree'd cats. With utter reliability..... Some lions have tipped the scales @ 170 lbs.
In those situations, those shots often can be measured in feet... 20 to 50ish.
