I hunt with my sks when i'm bushwacking while hunting deer... I wouldn't take a shot over 100 yds with it though.. I haven't had a chance to shoot anything with it lately.. the last few deer i killed were with my m14s or my sako 7mm rmag..
about 10 years ago i was hunting with my ruger mini-30 (not an sks, but same caliber).. I was using some 123gr soft points (this was back in the day when you could still get remington 7.62x39)...
i was walking a fence line that bordered a treeline, when i saw a nice 8 pointer about 120 yds on the edge of the field... he didnt see me as i was walking really slow and quiet.. when i saw him i froze and he just stared in my direction...
i happened to have a bush in front of me, so i slowly went to one knee and raised my rifle when i was under cover.. as i did that he turned around and started walking away from me towards the bush.. he was quartering away slowly so i aimed for his right shoulder and fired..
after the first shot he didn't even flinch, ran about 20 yards and stopped.. he then gave me a classic side profile shot on his left side.. i put the sights on his left shoulder and fired again.. again he didn't even flinch, and jumped over a 5 foot fence and disappearing behind a drop off on the other side of the fence... leaving me there thinkin' "holy crap, how could i miss that shot"?
I walked over quietly to where i last saw him to look for blood, and as i got closer i heard some thrashing coming from about 40 yds away in the treeline by a wire fence.. i looked over and his rack was caught in the fence and he was trying to get away.. i took another shot, this time at his neck just below his head and finished him off..
When i got to him, the first shot i took hit him in the back hip.. It broke his right back leg at the bone so it was only hanging on by "meat"..
the second shot hit him right in the left shoulder breaking his shoulder and almost severing his front leg at the shoulder.. front leg was just hanging on by a bit of muscle and skin.. the bullet didn't penetrate into the vitals...
it looked like the bullet disintegrated all along the left side of the shoulder and ribs... i've had the same shot on deer with a 308 and they dropped right on the spot..
i cant believe he jumped that fence with 2 broken legs and not even a flinch..
the third shot in the neck , from about 40 yds, killed him instantly..
if he didn't get tangled in that fence, i would've had a lot of tracking and extra dragging to do..
i take my sks out once in a while for deer, but only if i'm in heavy bush where the longest shot i could possibly get is about 100 yds.. If i'm in open country i take my m14s.
i know i could probably use a shotty for under 100 yds, but i prefer my rifle because i shoot it a lot.
a few things to consider..
this wasn't an sks, but a mini-30 (same caliber and bullet)...
barrel lenghth on a mini-30 is 18.5 ", i think sks is 20"..
this deer was about 180 lbs gutted...
the disintegrating bullet was probably more a function of the bullet, and not so much the rifle.
