Chill out man, I practice all year round with my bow. I've never hunted bear but I've shot plenty of animals. I'm only asking help to age and estimate the weight of this bear as I don't know much about them. Do us all a favor and don't take everything too seriously...
All I have to go on are the words you choose to use to convey information and the tone of your verbiage...
Your original post made it sound like you were a novice bowhunter and not terribly confident in your own skill... this is NOT a good mindset to enter the port of "big game bowhunting" with...
I don't need to chill out, we all (hunters in general) need to ensure that, as a group, we maintain not just legal practices but ethical practices...
Your subsequent post, also suggests an insecurity about the legitimacy of archery equipment (at least in relation to harvesting bears of larger size)...
To provide support not only for you but anyone reading this thread, archery equipment is lethal when used properly and within its limits, and can be used to cleanly harvest ANY game animal of ANY size on ANY continent.
My personal experience is forty years of bowhunting for big game species... including black bears... having harvested close to 50 bears with archery equipment over the years, ranging from 125 pound yearling "meat" bears to 550 pound Boone and Crockett boars... the arrow was as quickly lethal on the largest as it was on the smallest...
Enter the bear hunting game with complete confidence in your equipment... develop confidence in your archery skills on the range, and bolster your confidence by taking shots on game that are well within the limits of your abilities... don't push the envelope and take shots that are marginal for "you..."
Good luck on your bear hunt... I will echo what others have said, bear meat is among my favorite game meat.
