This zombie thread keeps coming back... for decades now.
Well, it's still a valid topic.
With respect to round-nose versus pointed "spitzer" type bullets, it depends on whether they are solid or expanding/deforming hollowpoints.
A round-nosed solid is balanced with more weight forward. It will tend to keep a straighter path while plowing through a target and therefore penetrate deeper.
Round-nosed solid/FMJ etc. also allow more total mass in the bullet within a specified OAL, and therefore higher sectional density.
Pointed, spitzer solid/FMJ bullets will have lower drag in the air, but their weight-rearward characteristic will make them more likely to yaw or tumble in a target and this can limit depth of penetration.
Pointed solid/FMJ are probably better at piercing armor. They exert more pressure within a smaller area when the tip strikes.
With hollowpoints, we're not really talking about pointed versus round so much as the width of the meplat and the opening in the jacket or cavity size in the monolithic. A really fine hollowpoint could be harder to open and might need more velocity, a thinner jacket or softer metal. A wide "round-nosed" hollowpoint can probably be made to open at lower velocities and under more adverse conditions. I think this would apply to JSP and similar bullets as well.
Around the time this thread started, back when some of you were toddlers, some knowledgeble people were recommending cutting the tips off Sierra Match Kings in order to get them to open up better.
