Spent the past couple of days looking over some rounds and Have decided to drop the ppc bolt head. I have been looking alot in the 6.5X47 Lapua and the 6 BR. Most of what I ave found dont make much sence to me. Lots of numbers. In layman's terms how do they compare? Application will be paper, steel, and varmints out to 700 Yards or so and no matches. I see that is is not uncommon to neck the 6.5X47 Lapua to 6mm. But All I have read is a little over my head interms of the write ups. And couldnt find much better here or on AR15.com. So can ya guys break em down in laymans terms? I reload and have no problem putting extra work to load up ammo. Rifle will be Built off of a single shot Savage target action most likely. But I may use a savage repeater. Stock will be a XLR chassis.
