Now this is a bit of an experiment that I have been doing to see just how many shots it takes with this rifle, before fouling effects accuracy.
As every rifle is different, I was wondering how often you clean your rifle and how long with different calibres you can go before you notice a reduction in accuracy.
Once a barrel is fouled they normally don't get any worse they just reach a level of accuracy that is eather exceptable or not.
If you never clean it it will probably never get worse.
I have never seen a barrel get better after 20+ rounds unless it was a very poor quality barrel
and the fouling actually filled the imperfections until it reached an exceptable accuracy.
I agree that you can over clean a barrel (Clean is clean no matter how much you brush and
Sometimes you have to shoot more rounds than the barrel likes before cleaning and have to live
with some accuracy loss.
The main problem with a fouled barrel is that it is very hard to predict point of impact(Calling
the shot) and I believe and have found that if a barrel is as clean as possible, it is also predictable
and if you can call the shot and trust the the call then conditions can be read easier and corrections
can be made with confidence.
Why buy a high end barrel that is near perfect dimensionally and with a non fouling finish and foul
it to the point that it is no longer any of these things?
This just my opinion and everyone has one, so shoot as much as you want to without cleaning
and you will never find out the true potential of the rifle.
When I first started working on guns I had lots of people ask me to look at there rifles because
they would not shoot like 'they used to'. I did all of the things that is normal for accurizing but
most of the time all the rifle needed was a good cleaning. Some took Hours to remove the
copper fouling and required using very strong solvents.
I received lots of kudos for the improvements in accuracy but had to tell them it was just very
dirty and required a proper cleaning/maintenance.
And in some instances had to show them how to properly clean there rifle and the tools to do it
with. And the rifles never came back for the same treatment.
When I was competing I found that the best shooters would not let you in on any of there secrets
but I have heard them say" Just size the cases and load there is no reason to do any of that other
crap. And dont worry about cleaning they shoot better left alone". but some of them were anal
and did every thing possible to win. but these guys were there competition and they were not going
to tell them any thing that would help.
I once had a distinguished master tell me don't believe any thing you hear and only half of what
