as above, not talking about factory barrels here but,
I cleaned mine right back to clean metal pretty much after putting about 70-80 rounds through it of varying intensitys ( not a match situation) and it seemed to shoot all over the place for at least 10 rounds before it settled down and a little bit of fouling in there again .
i realize everyones will be different but how long does it take yours to get it back in the groove again?
For my current Krieger 2 shots
My trueflite about 10 rounds
After total clean, so it gets a mild clean after 2 matches and seem to perform well like that
Why would a barrel need fouling to make it accurate?, does it have a bit of slop?..i have a match #5 on my hunting rifle and I expect it to shoot bang on everytime.
Trueflite?Quote:

theres no problem solving to be done, im just wondering if anyones does the same
and no, Bartlein
Who chambered it is probably as important question as what the make of barrel is.
All barrels are different and it sounds like yours likes a bit of fouling so just leave it longer and only give it mild cleans. I doubt you have a dud barrel out of bartlein it's more likely a combination of factors.
What is the chambering?
yes my 6mmrem (trueflite um) takes a few when real clean I found the best accuracy was if I done nothing but bore snaked a couple of times and oil and only clean proper copper etcetc once every 100 or so rnds in fact that's now what I do with all my centerfire barrels 22 rimfire barrels should only be cleaned once every 12 months under heavy use (I used to shoot atleast 200 rounds a week when I was competitive target shooting they shoot better fouled so if its clean I used shoot at least 20 rounds before shooting a match not a biggie with a hunting gun we are talking mm's difference
but like anything its finding out what works for you and your firearms you may find a clean barrel shoots best or the other way round and I know of guys that have rifles that like to be cleaned hard even in the rim fire circles
My 308 TF UM takes 2 shots from clean.
1st one is generally 1 minute low, next one about 0.5 minute, then back on my normal settings.
I clean with Butches Bore Shine, and only go to JB paste maybe once or twice a season.
Hope that helps.
My true flight shoots better after a few rounds, it's not huge and at first I thought it was juste taking a group to get in the grove but it's so consistent that I now think it just needs s couple of fowling shots. Still under moa for those fowling shots so for hunting it's a non issue I feel.
My annie .22 target rifle has the same trait but much more pronounced-I now hardly clean the barrel on it.
Most barrels get cleaned way to often
Dont over-clean it IMHO. I remove carbon fouling and that is it.Quote:

I have seen this effect on more than one gun, in fact it seems quite common. Better accuracy is not something I have observed though, or heard of anyone else commenting on only the vertical effect on a clean v shot barrel.
If anyone comes across similar geeky stuff i'd like to read ti by the way.
My Bartlein is within an inch of POA after a clean. And takes 2 or 3 to get back on.
But I never hunt with it, without a couple rounds thru it after a clean.
Velocity takes around 5 rounds to settle after a clean as well.
I only clean it now it's all setup maybe every 150 rounds.
HBN helps. I get next to no copper.
Best barrel I have had.

Agrred i was one of these guys when i started shooting that scrubed the liveing shit out of my barrels every time i shot even only 1rnd on a bunny or something i spent more time cleaning than shooting but after resurch and lerning lots i fugured out you don't need to all i do is snake it once or twice to make it look nice but as we all know its nothing morecthan lose dirt being removed then a light coat of oil before i shoot i remove the oil and its good to go after 100-200 rds depending in cal and barrel they get a spring cleanQuote:
