Yes, krochus, a 7.62x39 handload will run a 170 gr. the same speed as a 30-30...few times...then you will have destroyed the rifle (and possibly yourself)while trying to prove a point.
Oh please! 2000 fps with a 170grn bullets isn't going to overstress even the rattiest SKS anytime soon. The 7.62x39 has a somewhat low but throughly modern pressure rating, the 30-30 on the other hand has slightly more case capacity carries a pressure rating more befit of cartridges used when Victoria was queen of England. The performance envelopes for these two rounds pretty much overlaps everywhere.
So tell us what a 170 grain 30-30 bullet at 2000 FPS will kill that a 154grn x39 projectile moving 150 fps faster won't we're only talking 16grs diffrence here, hardly an earth shattering amount.
. a Sierra 140 gr. GameKing w/ a muzzle velocity of 2940 fps. The bullet struck the boar in point of the shoulder as he quartered right and towards me. When I gutted the hog, I found the bullet under the skin behind the left shoulder. If a hog that size (150 +/- dressed) wrecked a quality hunting bullet such as the one pictured, can you imagine what it would do to the run-of-the-mill 123 gr. SP?
The x39 bullet would probably have penetrated fully due to it's not being overstressed by the inordinately high impact velocity of the kill you cite
your impact velocities would have been around 2840 fps with a 140g cup and core bullet. I'm amazed it penetrated at all and didn't blow up like a varmint bullet. You should write Sierra a letter praising their product. Next time try to match bullet construction to the impact speed you're using them at.
