Applying cold therapy to a tissue injury, helps limit the inflammation by causing the blood vessels to constrict. This in turn helps to limits the blood flow to the injured site, which helps to moderate the release of the vasoactive substances and therefore helps minimizes the pain and swelling in the injured area.
Kangaroos go down easy with well placed .22LR shots, so a .17HMR or .22WMR will not be a problem. I've got both a .17HMR and a .22WMR, I prefer the .17HMR mainly because it shoots flatter, making it better for rabbits, and will easily take a fox out to 120m at least (provided you placed your shots ;)).angaroos go down easy with well placed .22LR shots, so a .17HMR or .22WMR will not be a problem.

Empty weapons don't kill people unless they are used as clubs and if the other guy still has ammo you are in big trouble.Back in the 'old' days when weapons didn't fire as fast (bolt action rifles) it wasn't so easy to run out of ammo. With semi-automatic weapons that only take a trigger pull it is much easier.Automatic weapons are even worse.In the heat of combat all a person has to do is clamp down on that trigger.mpty weapons don't kill people unless they are used as clubs and if the other guy still has ammo you are in big trouble.
