So after much shooting lead scrubbing copper removing etc my bbl just forward of the chamber and the last 2 in to the muzzle have oddly shaped Bright spots .At first I thought impacted lead from cast bullets but even the Rem oil 40X is not dirtying patches any more .
Is it pitting in an otherwise mirror like bbl or Impacted lead ? This is a 30-06' 110 LH 22" bbl 1-9 rt .
I'm really frustrated at this point , it's 6 weeks till opening day ,my rifle isn't up to it and I don't think that 760 is going to ever be a 300 yrd rifle .

options ;
new er shaw bbl
get rem 760 up and shooting 300 yr groups
get my 03 a3 drilled and taped
give up all together plan on a brutal stock to get into pistol or muzzle loader range .

300 yards is a very likely range in Reese river Nevada and this lottery system for tags well, it's been
6 years and 4 tries for tags .
