No, 7n6 effectiveness is over exaggerated. Its the same logic people use when trying to justify 5.7 terminal ballistics. You are better off punching a big hole over trying to make a bullet travel sideways through flesh. That "poison bullet" BS is pretty much Soviet propaganda, some SF guys who came back from Afghanistan who worked with former Muj who fought against the Soviets asked about it. The 'poison' in poison bullet roughly translates in Pashto to the poison in a wasp or bee sting. So 7n6 hit more like a bee sting rather than your wicked mad tumbling magic bullet.
Actually ballistically I think 5.45 is more like 5.56 2.0. Ive shot thousands and thousands of rounds 5.45 7n6 and Ive been impressed on how flat is shoots. The BC on that little 53gr bullet is far higher than 55gr or 62gr ball ammo and its doing it at lower velocity and lower pressure(my suspensions were confirmed via doppler radar regression :

Ive since completely divested myself of the caliber since the ATF pretty much killed it stateside which is a shame since the caliber had so much potential.
