I've got a Rem 700 5r on the way to me & I'm also building an AR-10 .308. I got some Federal Match 168 & 175 gr. & some 175gr. ammo on the SW group buy (Haven't received it yet}. Is there any inexpensive ammo for just shooting blocks of ice, targets where accuracy isn't important, etc.? Although I'm probably on the wrong forum to ask this type of question when MOA's are measured in .10's ? Thanks! ; ) Bill
