I have read all over the internet in my reloading books and other books and I still can't make up my mind. I have narrowed it down too these two. 6.5-06 shooting the 140gr Berger VLD .280 Rem shooting the 168 Berger VLD (hoping the rifle will shoot that bullet) This rifle is being built for deer and antelope sized game at longer ranges. Feel free to give me opinions on each and what you might choose. If you choose other and post a caliber I am not intersted in magnum's at this time. Thanks in advance.
