After months of saving and going back a fourth on which rifle I wanted, I have settled on a ruger international .308 and am going to order it this week. what I would like to know from you guys is when dealing with .308 carbines 18.5 in. is which bullet would suit me best for deer. light vs. heavy. also am planning on a vx1 2-7x33 Lupold. any thoughts on the scope?
