No one should have to borrow
your rifle to do this job. Trust
no one who does
not have/and is expert with their
own weapon of sufficient power.
That said, I'd get a (used if you can find one) Marlin lever-action 357Mag;
put a low-power (1x4) scope on it; and have someone you trust teach
you how to use it.
That rifle, that caliber, and that very personal capability addresses at broad
slew of your problems -- both present and future (and some you don't even
know about yet.
