It's an '06. I am a pretty experienced handloader and I've tried everything from 150's to 180's in conventional cup and core and all copper bullets. Tried 3 different powders now. The only time I can say it shot "decent" (1.5" or so) was right after I cleaned the bore with CR-10. I started seeing copper streaks in the bore really soon after cleaning it. Like within 5-10 shots.

I'll use the wipe out, start with a clean bore, and see what I get. I'll be sure to report back.
