I will be hunting black bear in eastern NC this fall with my NEF 50 cal. sidekick and 100gr of 777 from a tree stand and am looking for a good load for the hunt. I now use TC 250 gr. PTX for deer with good accuracy and knock down results. Randy Wakeman and others have recommended barnes 300 gr. mz expanders. Would the 250 gr barnes expander be to light for black bear? Send some recommendations. Thanks.
