And we go to the age old argument of whats better...being able to carry more rounds of accurate ammo, or carrying fewer rounds of more powerful....but oftentimes less accurate...ammo. This has been debated, redebated, and debated again, with no conclusive answers as to what makes more sense in a modern battle rifle. I have an SKS (and an AK, for that matter) and I like the 7.62x39 round. However, with its rainbow trajectory and whatnot, it may have short range punch, but lacks long range accuracy. As far as short-range "punch" goes, the SKS may have an edge. However, while the SKS may go through the barrier in question, the AR is more likely to be shot accurately. The SKS may go through the wall, but the AR could pull off a headshot when the guy peeks around it...again, precision over sheer force. Why use a machete when a scalpel can do the same job much more cleanly and precisely? Besides, now we are talking cartridge consierations, not platform. In nearly every way, the AR is more suitable for today's battle environments than the SKS. The debate of 5.56vs.7.62x39 vs 5.45x39 will never go away or get old to some people, but in terms of the rifles themselves, the AR is the clear winner IMO....comparing the AR to an Ak would be a more fair comparison, but even in that pairing, the believe todays AR's are superior in most respects
