So how long exactly does a barrel last?

How about 6 seconds.. :shock: Yes that is how long your barrel remains 'accurate' for.

The basis of this is a simple assumption, that a hunting rifle can shoot 3000 rounds before requiring a change, ( a number of calibers will start loosing accuracy at a much earlier round count), assuming a bullet on an average takes about 0.002 seconds to exit the barrel that is a massive 6 seconds of active life.

I never actually thought of it this way. My .22-250 will last all of 3 seconds :?

in India barrels last forever because, I guess there is some metallurgical secret. how otherwise you can see here so many 40-50 year old guns in mint condition.

greater tomorrow !!!

sacrifice today and get it tomorrow, he he he ... it twinkles ... well, I can consider that, but can you give any guaranties 8) .

more seriously, it is exactly a question, what I'm asking my self everyday 3 times at least, where this country is heading, for me picture is quite clear, get as many guns as you can today and you may no need to sacrifice tomorrow.

jefe,25/50 rounds,boys in UP get 10,in Punjab,Haryana,Delhi,(This can take all day,basically rest of the country) its 25,thats the secret for the time capsule.
MoA hi picked up a Rifle a .270 Win,Model 70 ( proud to say) Sr no 2607,the barrel still is like a mirror,shoots within 1/2 " at 100 mtrs,have been shooting 150 grns S&B, 120 Grns Fedral,Winchester Silver Tips and Power Shoks.Boss here we are still lucky :mrgreen: because of the system to get stuff which is 25-70 yrs old still in NIB condition :cheers:
PS; No doubt we pay through our a*****,for it but still here rifle/Shottys/Pistols/Rev barrels last forever :cheers:,3Ks of Bullets. Bullets@ 25 per year/3000 = ROTFL

Ah yes,the time honoured Indian way of holding up the rifle to the light and looking down the barrel.If it is shinny it is good.
