ohiohunter,

I mentioned the Sierra 7mm 160-gr HPBT being their toughest 7mm bullet because so many uninformed people believe that all hollowpoint bullets are fragile and "made to fragment".

Sierra's .277 140-gr HPBT is their toughest .270 bullet, according to Carroll Pilant, Media Relations Manager at Sierra. Sierra does not make a 150-gr .277 HPBT, but does make a 150-gr in SPBT.

I shoot the Hornady 150-gr SPBT and Remington 150-gr RN in my .270s.
