RE: Round Nose Bullets - Who uses them?
For short range kills, it's pretty hard to beat a round nosed bullet. The large "impact surface" makes for a hell of a thump. No, they won't fly 1000yrds in a straight line, and they shed velocity like water from a tin roof, but when it comes to breaking down game at close ranges (100-150, maybe 200), round nosed bullets are hard to beat.
Look at it like this: blow it up to a larger scale and slow it down-a spitzer type bullet drives like a stake, the point cuts it's way in and the bulk of the body just squeezes it's way through. A round nosed bullet doesn't cut a hole, it punches through like driving a baseball bat.
Sometimes rather heavy for caliber bullets are rolled in round nose bullets as well.
