There are many stories of bears taking multiple .30 caliber hits and still coming.
The AK-74 clone is probably in 5.45X39, approximately the same power as a 5.56X45 or .223 that is most common in AR-15 type rifles.
I never got the purpose of an AK-74. They don’t have the accuracy of an AR15 nor the knockdown of an AK47.
It appears the bear made a tactical error by retreating and coming back. If he'd kept right on going through the volley, he might have bagged the hiker.
Mine was 5.45X39 ... jammed a lot.
I have heard stories about .44 magnum rounds at point black range ricocheting off the skull of a grizzly bear too. I have a 500 magnum which I think is capable of cutting down a hardened utility pole but I hate to think about only having 5 shots in a pistol to deal with an enraged grizzly bear at full charge-especially if that handgun is of the short barreled variety.
Probably a 53 grain round only 13 grains more than a CCI mini mag .22 LR. Although its moving at 3,000 ft per second and if he was using Russian military ammo it has an air tip on it and turns on impact and does massive dammage. Thats what I use in mine. Very scary scenario though. Good shooting for sure.
Still thats the last weapon I would carry in the Alaska bush. I’d rather carry our Mossberg 500 loaded with slugs.
