請問這和
『L7 & M68 105mm旋膛砲使用翼穩脫殼穿甲彈APFSDS』
有什麼關係？
請拿出『旋膛砲不可（不適用）發射APFSDS』的證據出來。

rifled也是可以發射APFSDS(UK),厲害的甚至可以當ASAM(Russia),但是先天不良卻是不爭的事實;舉個簡單的例子,閣下的年紀應該有接觸過陀螺,當你把軸長增加到比直徑還要大時就會發現似乎界不是那麼的穩定了,甚至轉個幾秒後就開始"perturbation",這現象,同樣的也發生在APFSDS上頭,美國陸軍(AA)實驗過徑比超過8以上就會產生上述現象,同樣的困惱還不止於此,當在一定發射容積想要追求最大動能就必須朝細直外型前進,此時rifled加持,除了過高的徑比,應力作用施加在彈柱上確有發生過彈體自鍛
的現象!
