It actually does not. You can NOT taper crimp tight enough to prevent bullet setback. In fact, too ,uch taper crimp can actually reduce neck tenstion & proper neck tension is what prevents setback.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
