Read this one and thought there may be some interest out there:
In terms of shooting time elapsed, what is the average lifetime of a rifle barrel?
To perhaps make it easier I have included the poll to help you think.

I put 18 hours, just a guess:)
High Power or Low Power?
what size bore?
what colour barrel?
How long is the barrel? (Although I'm often told that it's the width, not the length of the barrel that's important!!!!)
Do you drive a big car???? :iconrofl: :iconrofl: :iconrofl:Quote:

I take 18 minutes.
Are you including sporting/recreational AND millitary ?Quote:

Muzzle velocity of a bullet is (roughly) up to about 1500 metres a second. Give it starts at 0, we'll assume an average barrel velocity of 750 metres / second
A bit short perhaps, but lets say the rifle barrel is 50cm long.
So, each bullet spends 0.5/750 seconds traversing the barrel = 1/1500th of a second.
18 seconds of barrel life will give you 1500*18 shots = 27,000 rounds fired
18 minutes = 1,620,000 rounds fired
18 hours = 97,200,000 rounds fired
18 days = 41,990,400,000 rounds fired
A 1.0 metre barrel would halve those figues, 18 seconds is looking good to me...
There's no "Who cares?" option... :(
Or WTF option. I hope burgs has tested this on his property, so we have accurate figures to rely on, but coaches analysis seemed good enough for me, 18 seconds for me
when will we know the answer? I can't stand the suspense any more!!
