Yep, identical as both cartridges have identical muzzle energy and in fact the 7.62x39 has the same or far better SD as the .44 Mag. A 123gr 7.62x39 bullet has the absolute identical SD as a 240gr .44 bullet, and a 180gr in 7.62x39 both shoots flatter than a .44 Mag and has a far higher SD, higher than even a 300gr .44. You can push a 180gr to 2,000fps in the 7.62x39 safely, and with it, there is absolutely nothing a .44 will kill it won't kill equally well. Out the the two, for versatility, the 7.62x39 is a clear winner as well as you have everything from $200 per 1000 FMJ to Hornady SST and VMAX 123gr for deer and predators respectively, up to 180gr if you wanted to go bigger with a little gun. The .44's neat, but it's a very niche gun.
