I disagree.

It could and most likely is right. The 180gr provides considerably more resistance, than the 165gr thus giving the powder time for that all important burn. If the 165 is slower, it's because the bullet is leaving the barrel before a complete powder burn is affected.

Now if the 165 was crimped, you might be able to boost velocity a bit.
