[QUOTE="6mmfan, post: 2396605, member: 120172"] the concave cavity does not actually give "more surface area to push bullet...". The total force along the barrel axis is unchanged. Some other things happen, and the mavens on this channel can probably speculate meaningfully about that. what's noteworthy to me, is the COG is moved forward, maybe affecting the geometry of the external ballistic behavior.
