My Son shot his first Whitetail with an Chinese SKS "Paratrooper" Carbine. One shot at about 70 yards and the fairly large Doe was down and out. A good Friend of mine shot his four pointer this year with his Yugoslavian SKS. Again, one shot was all it took. Some compare the SKS round to the .30/30, saying all things being equal the rounds are roughly the same. I always thought the .30/30 to be the superior round for Whitetail, being 170 Grains as opposed to 122. What do you think? The area we're in is mostly wooded with shot's from 40 to 100 yards being the most common.
My first SKS quite a few years ago, actually SKS's, were Yugo's. I got three of them, Gunsmith Special's, for $99 each, delivered. Their cracked stocks were easy enough to repair. And anyone who tells you they aren't accurate probably doesn't shoot very well-
(Wolf ammunition @ 100 yds.)
But the Yugo's are fairly hefty rifles and one day it occurred to me that I was toting around a rifle that was nearly as along and as heavy as a Garand, yet that fired a fairly mundane cartridge. So I sold two and gave one to my God son.
Fast forward a dozen years or so and Atlantic Firearms ran a sale on Chinese Type 56's and I couldn't resist. What I received was an 8 lb. 8.6 oz. firearm with grease in every orifice, nook and cranny, including the bore.
After cleaning all that mess off and tossing the bayonet and cleaning rod, I had a trim almost-carbine weighing a little over 7.5 lbs. that now resides in the laundry room gun rack or hanging on the tractor when I'm feeding the cattle, etc. I really like rifles such as these that use a box magazine as they make for a more trim, handy rifle. Should one so choose, extra cartridges or a full stripper clip can be carried in a pocket.
Again, don't let anyone tell you they're inaccurate. I shot this group while regulating the sights-
I keep mine loaded with handloads that run a Winchester 123 gr. SP somewhere north of 2300 fps.
Several Sunday mornings ago this nasty boar showed up about 110 yds. down below the house so I grabbed the SKS and poked him. He ran about 125 yds. and gave up the ghost.
So, to answer the OP's question, no they're not the equivalent of a 30-30 no matter how one twists and spins the ballistics of each. But in the role of a utility rifle for use on game no more than around 250 lbs. out to 150 yds. or so, I'd trust mine. When I shot the boar there was a bolt action .223 loaded with 65 gr. SP's in the rack next to the SKS, but I knew better than to use it!
