Can you guys post your thoughts on expansion/penetration of various .22 rounds? Like you I realize there are many shape projectiles out there in .22, hollow points, round nose, aguila, but aside from repeating the conventional notions, let's challenge them. I realize this is apples to oranges but I think it could be interesting.
I guess I'm not sure what you're asking, exactly.
Are we talking big game? Small game, or just any animal shot with rimfire .22 rounds?
Remington Subsonic = kills squirrels, pigeons, starlings, raccoons, opossums, and cats dead, when used in a Ruger 10/22, with or without a Gemtech Outback II on it.
CCI Mini-Mag = same, with a little more power.
CCI Stinger = same, but with bigger holes, more devastation, and more noise than any other .22 round I've used.
Any animal bigger than those, and I use a bigger gun. Remember... just because it's possible, doesn't mean it's a good idea.
