Dynamic qualitative bolt force measurements for investigating influence factors on the pushout effect of small calibre ammunition
A small calibre weapon system consists of the weapon and the ammunition.In the case of bolt action rifles during the process of firing, the breech is a rigid Chainwheel Extractor bearing which prevents the casing from being pushed out.However, not the whole pushout force is taken by the bolt.Due to friction forces at the casing boundary, the chambe
