clean barrel...bad accuracy

Hey everyone..I'm new to the long range hunting
..I posted some pics of my tikka 300 wsm awhile back shooting very well. Recently its been shooting awesome for me anyways... at 400 yds I was usually within 3.25 Inch group. The only cleaning.of the barrel I do is with a bore snake...the other night I loaded.some virgin brass I didn't expect great groups because its not.fire formed......but anyways I was inspecting my gun and saw some copper in the barrel. .so I ran hopped #9 solvent and a copper brush...followed by 10 dry patches..but when I went to shoot my next few rounds the gun has started shooting the worst it ever has and I'm wondering if it's because the barrel is not as dirty as it once was or because the Virgin brass I just wanted to see if any of you guys have had a terrible accuracy with a clean Barrel...my groups at 400 yards were about 9 inches! What did I do wrong???

Why did you take the copper out? That is most likly the issue new brass may be a factor but as long as all case prep was done and you have been full length sizing your reloads it should not have been very significant.

As a general rule dont remove the copper untill accuracy starts to decline just powder. But you learned something be sure to make a not of how many rounds it takes to get your accuracy back. All this stuff is very important in knowing your rifle and preventing future issues.

Re: clean barrel...bad accuracy

oh well no harm in that thinking this time, it tends to uniform our bores fill in tooling marks and such not. Very good for accuracy most of the time. The reason a lot of guys do a barrel brake in is to try to smooth out these little pits so the barrel fowles less.

I could never awnser that you said it your self there all diffrent. You are just going to have to shoot it and see assuming you changed nothing else. Make sure to write it down in your data book.

Re: clean barrel...bad accuracy

If you dont mind sitting through the video, this guy starts talking about having copper in the barrel and how often, if ever, he cleans it. I typically strip my copper if I am not going to be shooting for awhile, like after hunting season.
