My SKS shoots .308 caliber 130 grain HPs just fine. About 2" groups at 100 yds for the whole mag.
As far as the 220 grain bullets, why? Load some 150 grain .308 Partitions to about 2100 FPS and they'll kill anything you'll ever dare to kill with a 7.62x39.
And I'll bet you would get even tighter groups with the correct sized bullets. Heck, I can't even load some 150 grain bullets without horribly having to compress the powder charges.

Last I knew, most SKS wouldn't shoot 2" groups at 100 yds for 5 shots much less the whole magazine. What else do you expect from a $69 Chinese gun? If Someone would show me where Speer or Sierra makes a 130 grain HP in .311 caliber, I'll try it. Do you realize that the Ruger Mini-30 is made with a .308 caliber barrel and it shoots .311 bullets just fine.
After thinking on it,he may be onto something.Remember the .300 Whisper? sam.
That's exactly what he's recreating...just with a different parent case. The 7.62x39 will have slightly more powder capacity than a .300 Whisper case. I saw this combination mentioned for the .30 PPC on another website, but no load data was given.
According to QuickLoad, a 220-grain Nosler Partition seated to a depth of .308" will leave a barrel at 1850 if loaded with a charge of 26.16 grains of I3031 or 28.3 grains of Accurate Arms 4064 (NOT IMR). This charge produces - on paper - chamber pressures 15% below max. Chamber pressure is HIGHLY dependent on seating depth. If you seat this bullet deeper, the listed load WILL generate HIGHER PRESSURES.
Use these loads wisely as you would any information you got "from somebody on the web".
and here you have it 7.62x39 with a 220gr round ,this info come from a guy who was very help full .much thanks to this person who is a very on to it guy ,most 125gr sport shop rounds dont go over 2300fps so
125gr doing 2300fps =1306flbs of energy at 50yards an 1434flbs at 10yards
220gr doing 1850fps = 1472flbs of energy at 50yards and 1630flbs at 10yards
One thing that seems to be missing here is whether the barrel has a rifling twist rate that can stabilize a 220 grain bullet. (Remember, the .300 Whisper cartridge AND RIFLE was DESIGNED for heavy bullets at slow velocities.)
And with only 10 bullets to work with, I would think he wouldn't have any left to shoot at a hog by the time he properly works up a load and adjusts sights for what is surely going to be a different point of impact.
That would be one to talk over with the bullet mfg,SL11,good thinking.Possibly a cast bullet would be best.If I remember right the .30-03,parent cartridge of the .30-06 came out with a 1in14"or 1in12" twist and roundnose 220gr jacketed bullet. sam.
Several years ago I tried to work up a 220 gr BTHP load for my H&K 91. About the time the bullets stopped keyholing, I was starting to get extraction problems from the HIGH PRESSURE. Accuracy? Never even came close to it. Stabilizing those big bullets requires them to be spun at a certain speed; this is done either by muzzle velocity, or twist rate. You will never be able to achieve the necessary muzzle velocity from a 7.62x39 case without exceeding the pressure standard for the round, possibly several times over. If you'd like to re-barrel your rifle with a 1-8 twist barrel, chances are you could make it work, though you wouldn't get velocities much above 1200 fps. Forget the Russian - you want a short-range hog gun, either a 308 loaded with 180gr round nose bullets, or a 45-70 with whatever you prefer in the way of bullet weights. Leave the 7.62x39 to what it was designed for - inflicting injury on your enemies.

only have ten of them but will get more if any good ,i will only be shooting 6yrds if that ,308 45-70 are to big have used 308 for years but have dogs go deaf from shooting over them and the bullet can come out the other side and kill your dogs if i wanted i could just use my 7x57 but the 7.62x39 is ligth to carry
