Anyone noticed lower point cost for Hollow Points and Synthetic Tip?

Looking at the new update, a lot of guns with HP and/or Synthetic Tip now have cheaper costs. HP now can be priced at 15 points from 20 originally and Synthetic Tip can be found as 20-25 from 30.

But not all guns have HP or ST priced this way, and It may be because of weapon damage, which I noticed the reduced cost is mainly for lower damage per shot weapons such as ones with 20 or 25 damage, while 28+ do not have any discount for HP or ST if available. Generally only a handful of weapons benefit from HP such as 33+ damage weapons, but almost none of these have seen a price reduction for HP or ST. The few 20-25 Damage weapons that have ST may now benefit more to add other attachments much needed to compliment the lack of room 30 point ST had in the past. 

The only 33 damage weapon to have discounted HP is the M45A1 with a 15 point HP, which means you could add an optic and or suppressor if you want to run HPs and forgo the larger mag.
