Specyfikacja naboju.

[maziek]

W sumie nie ważne jakiego. Ważne, żeby dla danego typu (lepszy byłby do długiej lufy karabinowy lub pośredni, jak 5,56x45 czy 7,92x57) były co najmniej trzy naboje o takiej samej naważce a różnej masie pocisku. I żeby były następujące dane: masa pocisku, naważka, prędkość wylotowa, energia kinetyczna wylotowa. Zanalazłem dużo stron, na których podane są ww parametry ale poza nawazką.

Tu masz naważki w granach, nie ma co prawda masy pocisku ale jako, że to zestandaryzowany nabój więc może indziej znajdziesz... np do M80 można w normie NIJ 1001.04

Ale te grains-y to chyba masa kulki... po przeliczeniu na gramy oscyluje koło 9 czyli masy kulki a nie prochu. Właśnie nigdzie nie ma naważek...

A ja szukam informacji na temat amunicji 30-06 Barnaul, dokładniej interesuje mnie tabela balistyczna na dystansach większych jak 200m.
