Ten_Sleep,
Your not stupid, you just omitted the brand of bullet.
Sorry I've no personal experience with the Hornady version of 25 cal 120gr hpbt, I use the Sierra.
Hornady followed Sierra's lead by producing these Hollow Point Hunting bullets with a heavier/stouter jacket, much like the HPBT GameKing.
P.S.
Sounds like the hunting has been good for you in the Worland/Ten Sleep area.
