My 12 year old son is determined to hunt this upcoming season with a Weatherby Vanguard in 30/06. The gun is very light, has a synthetic stock and kicks like a mule. I'm trying to locate some 30/06 managed recoil ammo to get him started but I can not find any. I've tried Midway,Cabelas,Bass-Pro,Cheaper Than Dirt, and Able Ammo and all are out of stock. Has anyone have any suggestions as to where I can purchase some?
