If you need to borrow a rifled slug barrel I have them for Mossberg 500, 835, and 935. At 55 yards a bear spooked when my father-in-law cocked the hammer on his .45-70. You might get really lucky with a bow, but your odds are much higher if you head out with something that can reach out to at least 100 yards.

If it is near my neck of the woods, you can borrow one of my rifles.
