It's a roll of the dice if the rifle will like either of those bullet's.i bought a Tikka 308 hoping it liked nosler accubond 150gr to run kinda hard with cfe223 powder but no luck.it ended up shooting Hornady 165 btsp real well same as my other 308's and it shoots Hornady btsp 150's good also.i haven't fooled with all copper bullet's yet though still feel like they are made for California folks that can't hunt with lead...
