Sorry I missed this earlier
Hi-jacking thread a little. Don't know much about hand-guns but it seems odd to me that some of those rounds have a flat tip.
Is there any reason for this? Btw this is just idle curiosity.
The 'flat' tip or meplat does more tissue destruction than a round nose, or so the theory goes. That theory has pretty much proved been proved true over the years by the observation of wound channels.
The Keith Type bullet was the one most favored by handgun hunters in the days prior to deep penetrating, reliably expanging hollow point projectiles and still is by many.
.357 dia. 173 grain KT, .410 dia. 230 grain KT, .429 dia. 250 grain KT, .429 dia 265 grain Keith/Thompson GC(gas check), .452 dia. 265 grain Keith Type. The 230 grain .410 came from a mould once owned by Elmer Keith.
The hard cast bullets with wide meplats and sharp semi wadcutter shoulders, that cut a full caliber hole, do far more tissue destruction on game than other shapes of solid bullets do. Some handgun hunters still use them, because of their deep penetrating ability.
More of a side angle.
