That is a pretty stout load. I don't have a Hornady manual, but my Sierra manual is showing a max charge of BL-C(2) for a 175-180 grain bullet at 44.8 grains. Hodgdon shows a max load of 46 grains for a 175 grain bullet with a pressure of 50,300 CUP.
I would think that a slight reduction in bullet weight would be a step in the right direction, but there are too many variables. I believe that brass life has more to do more with the amount of resizing you do, neck tension and annealing your brass. In your case, it may be just too much pressure.
Powder in my .308 Win is between Varget and RE15.
I prefer Varget, but it is a pain to meter and has been hard to find so I have been using RE15 more lately.
Bullets, for paper, are 168 Sierra SMKs.
Bullets, for hunting, are 165 Nosler Accubonds.
