I can't seem to find a 5.56 NATO bolt action. I keep being 'offered' .223 rifles instead. This is an email I received from Remington: >Thank you for visiting Remington Country! We certainly appreciate you taking the time to write in with your question. Any rifle chambered for .223 Remington can not safely fire 5.56 NATO ammunition. The brass, case dimensions, and pressures are too high/large in 5.56 NATO ammunition for .223 Remington chamberings to handle. Should you have additional questions, please feel free to contact our Consumer Services Department at 800-243-9700, 9:00 am – 5:00 pm, EST, Monday through Friday. < Does anyone know of a 5.56 NATO bolt action?
