jag mag man..

you are the first person that this year had the problem. as i posted before on another site. gentleman shot a doe at 25yds and the deer ran 200yds with little sign on a double lung shot. he was using rem core-lokt's..
my opinion would be using a caliber like that where shots are that close. i would go with a premium bullet or something that would expand but not blow up on impact.
but then again i do not own a magnum so i cannot help you any further.
