Re: Barrel Life???
2 barrels come to mind for me. 1: My last 308 winnie. 2: As you probably already guessed my 300 RUMs.
I will start with the 308. I put between 3000 and 4000 rounds down the tube. I would say the usefull life of that barrel is over, not from shooting too much rather cleaning too much and using a particular cleaner too much. This was largely a test rifle for research and development of software and plain knowledge. Because I wanted fair, concistent and reliable results, I cleaned her out every 20 rounds with JB bore paste to get it down to the bare metal. Also during a 1500 round development stage it was cleaned anywhere from 6-9 rounds minus foul shots. This was ALOT of cleaning with an abrasive compound. Using this paste was also part of the experiment. I wanted to see if it would affect barrel life as some claimed. At some point in the barrels life it would no longer maintain accuracy with 180's and 190's. To this day it will handle the 155 AMAX with smashing results. But that is the only bullet it will shoot well anymore. The barrel today is still within specification but only by less than .0002" after having it air guaged. Shot out? No. Worn out? Definately.
Now the 300 RUM barrel #1. After putting between 1000 and 1100 rounds down the hole, it still shot some loads at .5 MOA to even sub .5 MOA. Not bad for a known barrel burner. My only gripe was that it was beating up my brass from excess pressure from the burned portions and the added friction that was causing. I am sure I could get a couple hundred more accurate shots.
I am not trying to knock the 300 RUM or any other RUM. I think it is a problem more with myself. I like to shoot too much. Not the ideal personality for a barrel burner.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
