"The Geneva Convention pretty much limits us to FMJ bullets"
Actually, contrary to popular misconception, it does no such thing. The Hague Convention of 1907 is an agreement to which the US is a signatory party, and it limits "projectiles ... calculated to cause unnecessary suffering". The Hague Peace Conference of 1899, a document to which we are NOT a signatory nation but which we have customarily observed, limits the use of bullets which flatten easily in the human body. It mentions softpoints and incised bullets as examples, but not hollowpoints. Limited use of hollowpoints by the US military has, in fact, been approved, tho their use is typically limited to opposing combatants who are not members of an organized military (e.g. insurgents).
