What kind of barrel cost $800.00?
I stole this from The Shooter's Forum
Bore Life of Centerfire Rifles
--------------------------------------------------------------------------------
From time to time we have members posting asking if anyone can predict how long their particular rifle's bore will last before requiring rebarreling. Perusing an old July 2009 issue of Field and Stream Magazine, it contained the following information as compiled by writer, David E. Petzal. I have edited the article for the salient points:
Every time you ignite a cartridge, some 5,000 to 6,000 degrees of heat is applied for a few thousandths of a second and at whatever chamber pressure the cartridge individually develops. This causes steel to melt. This is called "erosion". The more powder to burn and form gas pressure, the faster the erosion. A small case capacity with slow burn rate powders will not erode as fast as large (and overbore) capacity cases with faster burn rate powders. A fast burn rate powder will burn hotter than a slower one.
Stainless steel resists the damage of heat/pressure more so than chrome/moly steel.
Now, some generalities of useful barrel life, based on factory loaded standard ammo:
.223 Remington (3,000 to 4,000 shots)
22/250 Remington (2500 shots)
.270 Winchester (3,000 shots)
7mm Remington Magnum (1,500 shots)
30/30 Winchester (6,000 + shots) He says "God only knows, never saw one shot out!
30-06 (4,000 to 5,000 shots)
.300 WSM (2,000 shots)
.300 Weatherby (1,000 to 1,500 shots)
.338 Winchester Magnum (2,500 to 3,000 shots)
An interesting side note: gunsmith Melvin Forbes told Petzel he saw something like 3,000 rifles come in for rebarreling, but only found 3 that were actually shot out. The other 2,997 were due to neglect in not cleaning or improper cleaning.
Moral of post - don't overheat the barrel while shooting (should be able to keep hand comfortably grasping barrel), use the slowest powder that provides adequate accuracy, be knowledgeable of proper cleaning techniques and clean when accuracy tails off.
