Had a sow/young boar come into a cow call a few years ago. Had a solid bead on her at 50'ish yards and was ready, had she decided to charge instead of turn tail. Took 2 stern 'GET OUTTA HERE'S' before she took off, but she coulda just as easily pushed the issue and 50 yards is nothin' for a grizz to eat up.
