其實120mm炮同125mm炮的差別大唔大?

蘇聯的125炮威力是不是大過120?
Many people have a bad instrinct or belief that tank gun the bigger the better..........
THIS IS NOT RIGHT.............
You may think guns length and diameter dictate a gun powerfulless, but you are dead wrong. it all depend on the shell u are using.
To explain this, you need to always know the bigger the gun, that can only mean the more explosive or gun powder that a round hold. That translate to virtually nothing.
Modern Tank warfare highly depend on the shell responseness to the armor and the penetration power were direly related to shell design but not how heavy the round are nor how much gun powder the shell hold. More HE will not push harder fdor your round. Rather the design of shell itself do make a whole lot of diffferent.
蘇聯的125炮威力是不是大過120?
Would have to say, no, infact russian 125 gun perform worse than US/Germany 120 gun, why? Cos in order for a gun to fire ATGM, the gun itself have to adapt to a system to take reduced gunpowder (otherwise when the AT missile ignite inside the gun barrel and there are still gunpowder residue there, diaster)

蘇聯使用125mm口徑火炮，個人認為是要同時配合導彈發射之用。而因為加大了火炮口徑，卻令炮彈體積加大，間接減少了載彈量。而且更因炮彈重量加大，而要發展自動裝彈器。
其威力是否大過120mm火炮就見仁見智，因其炮彈初速是慢過120mm火炮之炮彈，所以估計破壞力是差不多。

体落去。120mm 火砲是更加POWERFUL 125mm 火砲，因爲所有USA 的 MIA1 M1A2 都是用120 火砲的。在海灣戰爭中，125MM 火砲是不敵120MM 火砲的。
本人認爲120 MM 火砲是較中等而适中的。但125MM 卻太大口徑呢！！！！蘇聯想超越美國，太勉強啦。。。。
