That sounds a lot like the 6.5 Grendel.ħ.92x33 Kurz is, on one side, pretty anemic with only 1300 joules or so (compared to the other rounds), but that also meant reduced recoil impulse (and as result, reduced recoil energy). Neck it down to 6.5 - 7 mm and you would have about the ideal combination. The 7.62x39 is probably the best overall, but not a lot to pick and choose between them.

The 7.62x39 and 7.92x33 bullets limit range compared to the 7mm bullets of the same weight. The 7.92x33 and 7x43 could user a little more case taper.

276 Pederson is considerably longer than the others, which limit the weight savings in rifle and ammo load relative to the other cartridges. 280 British, the concept of an intermediate power military cartridge of a 6.5 to 7 mm diameter was far from dead. 276 Pedersen in caliber, bullet weight and velocity. 280 British cartridge, which shared ballistic similarities to the. 276 Pederson and 7.62x39 win out there over the 7.92x33 and 7x43, however they all work fine in automatics. Interestingly, the British studies on various cartridges culminated in the. For use in automatic weapons a slight case taper improves extraction in a dirty chamber. In practice there's unlikely to be any significant difference between them. Long skinny bullets rather than short and squat bullets. 276 Pederson were probably the most lethal, and longest ranged. My question - Couple of questions is any of the above better to use with automatic weapons than the other and is the terminal effects on your enemy better with one or the other. I asked basically this same question years ago.
