Yes, short rifles and carbines.
Mini 30, SKS, MN 44 and now two LE #5s "Jungle Carbines" (plus a fun #4). Only iron sights.
These small LEs are so handy/lightweight, but still have a deadly bite-like a short cobra.
Wish I could find the brief Internet description of the encounter with a charging grizzly. The guy had stopped to take a leak, and his Jungle Carbine stopped it with four shots.
Not being a hunter, my question is, where are the best places to hit a large bear with the .303, in the head or neck?
