I understand the added ragitity and cooling but as a way to strengthen a barrel so it resists damage? Has anyone ever seen a bent barrel caused by being dropped or knocked around?
Clear this up for me JonM.
ive seen soldiers bend 20" a2 semi heavy barrels just monkeying around. if you drop a rifle off the top of a hmmvw or 5 ton or similar vehicle or fall on top of it its gonna bend. but i dont think a fluted barrel would have helped. fluting done right dampens the effect of vibration possibly aiding accuracy but i dont think its enough to notice in anything but benchrest and those guys prefer super thick barrels anyway. if the bend isnt bad there is a technique in the m16 armorers manual to hand straighten them in the field.
bends happen a LOT in hand to hand combat. especially in ww1 and some in ww2. doesnt happen as much as times have progressed.
personally i think its a non-issue since life or death no ammo left and your afixing a bayonet... bending a barrel is the least of your concerns. the rest is just clumsiness or neglect or negligence and easily avoided
the main purpose is heat reduction by added surface area. a fluted barrel has a higher sustained rounds per minute than a similar non-fluted. i think colt rates their m4 carbine at 12-19 rpm for sustained fire. a shorter barrel also has a higher sustained fire rate than a longer identical barrel because more powder is burnt outside the barrel than inside but as you know it also decreases velocity.
my personal preference for a rifle im carrying is lightweight barrels. im no longer active duty military and i doubt im ever going to be in a frontline type fight having to maintain a higher rate of fire in a prolonged battle.
my savage model 10 308 is fluted and i can sustain a 12ish rpm and it doesnt get too hot due to the fluting. of course external air temp has a lot to do with how fast you can shoot without extreme overheat
