Yep! that is why I am using the bore buttons to insulate the patches... If you look at the .015 patches - I do not see them as blown... you can see where the ball sat and where the patch pressed on the side of the bore.. that area is not burned at all - the edges of the patch are frayed - but they fray when I pull on them. On the other hand the .018's are terrible can not figure out why the powder blows buy them but not the .015's - unless I am cutting them on the way down....
