I just bought a 30-06 Savage 111. The cheapest ammo at Wallys is Federal at about $14.50 a box of 20. I can get Ruskie ammo; either Golden Bear at about $12 a box of 20 or Wolf Gold for about the same price; both are somewhat less expensive than the Federal. (BTW: My Wallys has three different grain Federal from about 145 gr to 180 gr) Anyway, the Golden Bear is steel covered with brass and the Wolf is actual brass cases. Will it do any harm to shoot this stuff? How about steel case 30-06? Be gentle; I don't use steel case in my AR15 or Su16 but then 223/5.56 is cheap anyway.
