Re: Good load gone bad?? Or at least i think so.
Could be a lot of things.... any one or a combination of things mentioned. Another possibility is may you have damaged your crown and/or throat while cleaning. A good gunsmith might be able to give you an opinion on that with an inspection.
It's also possible you are not getting all the copper out when cleaning. What product are you using? Bore Tech Eliminator and Wipeout are the best. others will leave copper behind when showing white patches.
You will never know how much it has cost my generation to preserve your freedom. I hope you make good use of it.
