What's the reason to choose a round nose bullet instead of the normal pointed options?
Thanks.
(edit: Talking about shooting rifles here, not pistols)

What about hollow points?
What about the point hardness?
What about what you hit, bone or soft tissue?
What about impact speed?
There are a lot of variables.
And I'm inclined to think the "brush bucking" argument is an old wives tale. But may well be proven wrong.
This could get interesting.

Bullets of the same weight in the same calibre have the same S.D no matter what the shape.
For example, a 150gr spitzer in .308 has the same S.D as a 150gr roundnose in .308. That is, they both have a S.D of .226
The heavier a bullet is for calibre, the higher the S.D.
Ballistic co-efficient is dependent on bullet shape. Perhaps you are confusing the two?

RN Soft points can open up quicker at lower velocities depending on design with more frontal lead exposed.
For me the main reason as was mentioned earlier. Round nose means more weight for a given length which means more case capacity for powder when you start to get up to the really high bullet weights and then more velocity
only worth it for large game at short distances.
ie example with guess velocities.
Hornady 220gn .308 Round nose length = 1.283 in
Hornady 220gn .308 eld-x length = 1.63 in
Running both bullets out of a 30-06 you might get (guess) 150-300 ft/sec more out of the Round nose.
that is an extreme example and the velocity would quickly drop for longer range shots with the RN but for a charging buff at 25m the RN would be the better choice.
