wolf / silver bear is not good for the modern rifles..... those bullets use "steel" jacketed bullets (not copper), they WILL FAIL the magnet test (which means you can not shoot them inside in-door ranges) plus....... why would anyone want to spit steel slugs out of their nice barrels ? that would just wear out your barrel so much faster.....
If you want cheap '06 ammo, you have couple choices......
--buy military surplus FMJ NON-CORROSSIVE ammo from websites like cabels, cheaperthandirt.com, etc
--buy a 308 converter, 308 ammo is cheaper than '06 (here in michigan, we have gander mountain stores selling 308 147 gr FMR for $70, 400 rounds...You can place the converter inside your gun that way you can shoot 308 rounds in a 30-06 gun (which is belive it be pretty safe)
--3rd choice, and this is not one that I personally do, is reload (but if your not into that, I totally underestand)
--walmart sells a box of 180 gr soft-points remingtons for about $12.50
--Gun shows (I never been to them but I heard that bulk ammo is pretty cheap there)
