Just a thought regarding the rate of fire. Clearly a semi auto is always going to have an edge over a bolt action. But the Lee-Enfield is arguably the fastest military bolt action ever produced. During WWII the British taught quite effective close-quarters quick fire techniques for the Lee-Enfield. 5 shots in 4 seconds was standard (even faster in the hands of an expert), and with decent enough accuracy to ensure consistent hits at short range. This is not much worse than a semi auto. At any rate, few people could fire a semi auto chambered in a cartridge as powerful as the .303 much faster than that without losing control over the weapon. Check the SMLE section of Fairbairn's All-In Fighting (1942) for details. Paladin Press has published a good reprint lately.
