What about a good old fashioned pointed soft point, like a Remington Corlokt? I have a .22 Savage HI-Power and use 70 grain psp bullets on deer. Works O.K. and is loaded way under a standard .223 factory round. I never shot a deer over a hundred yards with it, and am not sure it would be a good idea, but out to a hundred yards the psp bullets work fine.
