traditional bullets do not work on robots.
Robots would have to be made of light weight components or would have to be large, wheeled vehicle, type machines. A 30-06 would have no problem putting down any walking type robot. If the robots are armed they will have to stop and brace themselves before firing a weapon or the recoil would flip them over. Without a nuclear power source or some "other worldly" power source they'd have a lot of trouble building one with enough weight and armor to be useful as a solider.A .308 FMJ can punch a hole through 3/8" steel at 300 yards. How heavy are these robots going to be?
The wheeled versions would be more able to fire and move at the same time and could be more armored, but a simple log in the road or a set of stairs would defeat them.
