>>19086902>bullets at typical handgun velocities must physically touch tissue to damage it as there are no remote wounding effects caused by the temporary cavity exceeding the elasticity of human flesh at these velocities>in order to successfully incapacitate a threat via physical damage vital structures must be damaged>only rounds with adequate penetration can reach these vital structures>shot placement and penetration are the only factors that determine the effectiveness of any given handgun round to cause physical damage to vital structures>the only downside to maximizing penetration with bullet selection is over-penetration>if you don't care about overpenetration there is no reason to ever use hollowpoints because they limit penetration in exchange for an increase in surface area which is only a theoretically worthwhile exchange if you know for a FACT that expansion will not limit your penetration to unacceptable levels>round nose bullets are inferior to bullets with square shoulders and flat meplats in their ability to cut tissue>assuming two rounds have equally adequate penetration the better round of the two will be the one you can shoot faster while maintaining accuracy.Hits count. First hits count most. Carry whatever gun/caliber combo you can make fast accurate hits with. Everything else is marketing bullshit designed to have you paying for overpriced meme ammunition.
