If you want to see what the nose design actually does and does not change, get your pellet rifle out! Flat noses knock squirrels a foot sideways off the limb, but if there is any wind or they are a little farther out there, the chances of hitting them isn't good because the design isn't for that kind of shooting. In phone books, they punch a sharp hole and the force cone spreads quick to stop them. The harder you shoot them, the bigger the force cone, but the penetration does not increase much.
Pointy bullets at first guess would seem to penetrate better. They beat the wadcutters but not by a lot. The straight sides produce a force cone almost as big as the wadcutter does, only a little deeper in the book. The force cone does not mirror the shape. There may be some additional ripping past where the bullet stops over what the wadcutter produces. It is still pretty much flat like a wadcutter produces. They fly ok at the middle distances, but still have the wind steerage problems of the wadcutters to a degree.
The true round nose that is about 2x caliber in length or a little longer produces a force cone that that is not as well defined and it is shaped like the nose with a center that is much deeper than the outer edges. It flies long distances better than either of the others does in the same conditions. They do not have the pronounced impact on game as the other two unless you add a hollow point. They penetrate better than either of the others by a large margin. Naturally, the force cone is much smaller than the others also.
I did not have any hollowpoints when I did the testing, so I can't say definately what effect they will have.
Throw away what you think you know from your modern guns. It does not apply to the slow soft lead bullets used in traditional guns. The air rifle info is close in the rifles and almost perfect in the pistols.
If you want to see for yourself, get some thick phone books and do the tests yourself. Count the pages penetrated, the number of pages torn past where the bullet stopped, and measure the force cone that is easy to see and measure. If you can get the old type books with the tissue thin pages, it is even easier to measure and record the results.
I use a target minnie for one reason in my slug gun. It shoots that bullet better than anything else I have shot thru it. I don't need long range capacity, so the nose design doesn't bother me very much. If you are strictly looking for range and penetration, then a good roundnose just about 2x times bore or a little longer is the bullet you want. Cecil at Precision is the best commercial source of long range hunting conicals that I know of.
At normal traditional hunting ranges, the added penetration means that you can shoot a lighter powder load to produce a pleasant to shoot combo and still be sure the bullet should exit most of the time.
