Не увидел я в сообщении Daniau попытки создать новый патрон. Он выдвинул тезис, что при масштабировании пули калибра 8 мм в калибр 5,56 баллистический коэффициет изменится. Проверил - написал, что ошибся и коэффициент остался прежним. Все.
А про новый патрон я читал тут:
Why is there such an apparent disparity between peacetime testing and wartime experience? Possibly because what is mainly studied in peacetime is the probability of incapacitation, which is a combination of the hit probability and the energy delivered to the target. On these measures, 5.56 achieves acceptable accuracy at most combat ranges and delivers enough energy to be lethal so, given that the ammunition is half the weight of 7.62, it shows up very well. The problem is that this takes no account of any other factors: obviously the ability to punch through barriers and other cover; and in particular the difference in the suppressive ability of the ammunition – in both of which the 7.62 substantially outperforms the 5.56. Given that the overwhelming majority of small-arms ammunition fired in battle fails to cause any casualties (as explained in the article "Towards a '600 m' lightweight General Purpose Cartridge"3), suppression is the main practical effect of small-arms fire: pinning down the enemy so that they are unable to return accurate fire, or prevent your fire team from manoeuvring into a better position to press home their attack, or escape from supporting fire from mortars, artillery or aircraft.
