Any Round Nose Fans Left

[Rocky Raab]

Roundnose bullets are often more accurate because being shorter, they are more stable in flight. At reduced velocity or with marginal twist rate, that makes them more accurate.

All bullets deflect if they hit something between the muzzle and the target. As there is no way to completely duplicate a shot that does deflect with another shot using a different bullet, the argument cannot be proved either way. All you can say is that one bullet may or may not deflect more than another bullet - which says nothing at all.
