I don't believe you will shoot out a barrel after 1000 rounds from a 300 WM, 4-5 thousand maybe. I have been told that an average life of a 22/250 is about 5-7 thousand. A 223 much longer. As far as barrel material is concerned, a harder barrel will not nessessarily give you more wear resistence. Using your automotive cylinder as an example, they are made of cast iron, not steel. They are not very hard at all but very wear resistent. If there were better materials for gun barrels than they are using today you can bet some one would be using it. As far as a barrel shooting better after 100 or so rounds, If a bore is a little rough it probably will, If its too rough it probably wont without lapping or pollishing. Just my $.02 KN

barrel life
I would be willing to bet that 99.9 % of the guns out there recieve more damage to the barrels from neglect and misuse during the anual cleaning process than any of the shooting they recieve. The average Hunter that buys a quality rifle today and takes good care of it can usually expect it to last several lifetimes.

JIMBarrel Wear
Guys I got bad news. In a M-1 30-06 barrel wear starts hurting accuracy at about 8000 rds. By 10 you'll have to replace the barrel.In NRA Highpower comp. you'll shoot 1 match min. a mo., down here you can shoot 3 a mo. plus pratice.In 5 yrs. you'll need a barrel. Hart & Douglas make great barrels. Douglas makes a XX SUPREME barrel that is straight when finished. Why is that important? Because most are bent & have to be hammered straight. When they get hot they bend back to where they were; causeing shots to string. This is true of all barrels. A .264 mag will degrade acc. in as little as 800 shots.Big Bill, a .300 mag will wear a barrel early;it can start in 1000 rds. The problem is OVERBORE;the relationship of case cap. to bore size. You have a big case some holding over 100gr. of powder burning real hot out of a tiny hole in the case.It is somewhat like a cutting torch. There is a guy a few miles from here that replaced a 30-378 WBY. BARREL after 600 rds. He must be a bear for punishment. I have a Columbian 98 mauser in 30-06 I am about to rebarrel because it is shot out. The 30-06 last so long brcause it is a more balanced round. I know .223s are supposedto be good for thousands of rds. but I can't remember avg. barrel life right now. For hunting purposes, you need to practise shooting at least 1-200 rds. before season opens but a rifle in 30-06 will last a lifetime at 100 rds a year.A decent barrel installed can be had for a couple hundred if it is a common rifle. A match barrel like the XX will cost over200 for the barrel in a box.
