Re: Barrel life
Barrel life is effected by many factors,
Overbore cartridges are the worst offenders.
High Velocity is another. and the type of powder used
can also shorten barrel life.
Throat erosion is the first thing to happen then the crown
is next but I have seen rifles in military armories
with over 50,000 rounds that still shot well.
As you know the military uses ball powders and keeps velocities below 3000 fps on all but the special purpose
weapons (sniper,etc) to minimize throat erosion.
Some people have shot thousands of rounds with no loss of
accuracy with large overbore cartriges like the RUMs.
So buy what you want for the intended use and clean as
often as possible and when accuracy falls off try a
thorough cleaning as someone suggested and then take a bore scope and look at the throat, If it is eroded have a gunsmith set the chamber back.
Another thing to consider is a stainless barrel, they dont
erode as fast as cromemolly and can be left unclean longer
without problems (A hunting trip of a few weeks max)
A bore snake or dry patching after each shot helps hold
down the carbon buildup when hunting.
Good luck and good hunting
