then answer me this.

How can you tell if your barrel is round or 11 degree. my looks round... all barrels look round.

And, if i did damage my crown in anyway at all, would it immiedetly through my accuracy WAY off or would it be hard to tell.

Ok, if you look at the end of your barrel, you might have a target type crown or it looks flat like you cut it off with a saw. But if it looks like you took a file and smoothed all the way around the end of the barrel and inside, then rounded. On a Ruger 10/22, it is just flat. Not 11degrees. You know where the inside of the barrel and the crown meets. You want that as square and even as possible. Thats where damage might occur.

It didn't sound like you did any damage. I wouldn't really sweat it but make sure in the future your careful around that area. Another thing, with a 22LR it won't have near the effect as a 22-250. Reason is, when the gases are escaping, they generally are not as high with a 22LR. Don't worry so much about it.

i dunno, there are these little lines that go through the barrel. There is a part on the crown that looks a little different then the rest i think, but maybe i'm seeing stuff.

like i said, if you did any damage to the crown would it be noticable in your groups or not? i'm wondering if i may have done some and loosened my groups a little. or is it one of those things that if you messed it up, you would know for sure byt the wau that it shoots.

Would i have been shooting groups in the inches if i had messed it up?

Like I said, with the bullet your shooting at the range your shooting at, it would be hard to see much degration in performance due to crown damage. The most you will see with the average shooter is like using a high powered rifle and shooting >100 yards or for people who shoot >50 yards with 22LR. With bad crown damage, you would see groups open at 100 yards by twice or so. So if your high powered rifle was consistently shooting 1 1/2" groups, you might see them open to 2 1/2" groups or so. Reason I know, cause I have damaged a crown using those three peice rods about 10 years ago. Or if you have a real shooter 22LR that gets .5" groups at 50 yards, you would see them open to maybe 1.5" or 2". Bottom line is the effect is very subtle and kinda sneaks in on you. You usually blame the wind or your shooting skills or dirty barrel or bad ammo. The effect usually takes place over years of cleaning like you do. One more tip, is you are shooting boattails, the effect I see is greater with crown damage. Alot of the same guys I see preaching about crown damage, go and don't use a bore guide and scrape their thoats. Which in my opinion is worse than crown damage. Bad cleaning practices usually add up to throat damage and crown damage.

the .22 i own is know to be a real shooter. very capable of half inch groups at 50 yards.

Like i said, i can shoot dime sized groups at 25. If i can keep my groups under an inch at 50 i don't think there would be crown damge. At 25 i can wack the bullsye every time, no questions asked. haven't got to shoot it at 50.

It still should shoot about a half inch at 50.

Here's what I've done with the aluminum 3 piece rod. I chucked each section in a drill press. Started out with 320 grit sandpaper and with the drill press running sanded the entire length of each piece and put a taper on each end and rounded the edge where each section meets. I then went over them with 600 grit, 000 steel wool, and finished them off with polishing compound. I have always cleaned from muzzle to breach with no loss of accuracy. My question is will this work or should I spend some money on a better cleaning set up.

do you think damage could exsist if I'm shooting 5 shots in the 10 ring/bulleys at 40 yards? i can cover my groups with nickkles at that distance, do you think there is room for crown damage?

really all i'm wondering now is, does your accuracy degrade as the crown damage get worse, or if you damage it, even in the slightest, will you have groups open up an inch
