Several years ago, super light (95 & 100 gr.) Soft Point 9mm bullets were all the rage with law enforcement. However, these were flat points, not round nose, and while they did expand, had a very poor reputation as a fight stopper and were abandoned. Reason being is without getting too technical, a bullet requires a minimum amount of resistance (friction) from the tissue it is penetrating to deform into a mushroom. So even though it has the flat point it gives enough to expand but due to the round nose it tends to do more what Gene is suggesting above.
Also one must keep in mind that allot of this depends on what it is being shot from, Handgun vs Rifle ect. The early bullet makers had problems getting the basic round noses to feed properly, and the solution was found by cutting the tip off. Depending on where you live and what gun historian you speak to, this story will have different people involved, but it boils down to getting a reliable bullet that didn’t jam or misfire as much as early designs. Over time, as bullet and casing technology improved, other more advanced bullets showed up. But these lead round nose flat point rounds remain popular to this day – over 100 years later.
The best thing about this bullet is that you know it will work as intended – years of use in the field and on the range have proven this. Those who want to get that old-school experience with a lever-action rifle or single-action revolver, like the Colt Peacemaker, will want an authentic round to go with it and this is going to be the number-one choice for most but, as stated above this is over 100 year old tech. It is basically the next technological step above round nose ammo. So again depending on the intention for use, If self defense no way, for hunting big game no way. Not enough take down (stopping power) or tissue damage for my taste. For target practice hell yeah, cheaper than using core lock, hollow points, Nosler Partition type ammo for slinging at paper.
