How many barrels have you replaced in the last two years? If you have not replaced a barrel, have you lost accuracy?
I have been talking with several shooters who seem to be replacing their barrels at an alarming rate. It appears that some shooters aren't even getting a full year of competition out of a new barrel. What seems to be the problem? I have notice that over the past couple of years, there seems to be a lot of gritty residue left in the barrel from the ammo. It appears that the primer (I think it is the primer anyhow) is leaving a very sandy like material in the barrel, when the next round is fired, it is pushing this grit into the barrel and seems to be sandblasting the barrel. If you can, take a bore scope and look at your barrel. I think you will find what appears to be sandblasting at 6:00 down the barrel.
I have pushed a patch through and collected this material from a couple lots of my ammo. My ammo is two years old. I have some Lapua and Black box Eley. Every lot of ammo that I tried had this real gritty substance in the barrel. I then used some of my old Gold box Lapua. It was completely different. The residue left behind seemed to be more of a powder material. I know people who (when we use to have the gold box Lapua) had over 50,000 rounds down the barrel and it was still shooting well. Now, it seems that if you get 5,000 rounds through a barrel you have done well.
I believe our ammo is killing our barrels. Has anyone else noticed this and what can we do about it?
