For the 1st time, I'll be slaughtering a 1200 lb cow... Just wondering if it would be better to set up 50 - 100 yds back and put a hunting round through the ear or get up close, above/between the eyes with a shotgun/handgun? Considerations are bleeding it out promptly, either case, this should be acheivable. I've never shot something up close & it seems to be a tougher thing to do... I've had some farmers tell me a .22 and others say a shotgun w/ shot shells up close. For the 'newbie' what would be the least stressful for both parties involved?
