130 or 150 gr
I shoot a rem. 700 .270 and I use the new 110 grain Federal Hyper velocity an they work great they shoot real flat out to 350 yrds and beyond. The 130 and lighter bullets in the 270 are designed for deer sized game the 150 gr. are designed for elk and bigger game with thicker skin and heavier bone they don't expand as fast so they penetrate deeper to get in the vitals of larger animals so for deer I say you need 130 or lighter bullets in the 270 because they expand faster and deliver more of their energy in doing so.
