Naw, a 30-06 will go right through blocks. Better use two feet of sandbags with PSP or railroad ties to hold in place. The ceiling should be at least four feet of dirt on top of heavy timbers or tree trunks. Build it on the ground floor. Better set steel gridding out about two feet from the walls and ceiling to help defeat RPGs and morters. The door is always the weakest point so don't put one in. Use 20 feet of serpentine entryway instead. It'll be darned expensive but ya get what ya pay for and ya can't put a price on safety!
