hey guys whos out there , i have a couple of question , here goes , on a recently new rifle, about 60 or 70 rounds thru it , and its been cleaned to the point of no blue coming out on the patches , when i look down the bore [ ps its not loaded] i can see what looks like copper in the deep part of the lands is this normal or is it still fouledmy second question is on some of my older rifles it looks like the stocks are bubbleing on the surface , would it be possible to put these rifles out in the sun to correct or stop it , the worse 3 are rugers m77 s any ideas ?

1) does it shoot straight?

2) is wood or sealant the problem?

can you post a pic of the bubbling on stocks. It would help you get a better answer.
