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 .

Sounds like lead to me, but others may have a different thought. You say you've been shooting cast bullets, so I'd say that is what it is. I would get a solvent that is specifically for removing lead and work with that.

If that doesn't work, is there a gunsmith nearby that can remove it for you? You have 6 weeks so maybe there's time to get it done.

Are you saying the gun does not shoot acceptably now?

Try using Kroil. The oil will get under the fouling and after it sets for a while you will see it flaking off.

I live an hour from walmart. 6 smiths about a hundred miles away. Pretty sad that it's cheaper to buy the tools and bbl than take it to a smith.

Kroil is familiar but unknown at the moment. Can you give me a normal source.

6 years ago it was capable of 5 touching when I did the last serious load and bench work for the hunt now my best those loads go in to around 2 inches now. As for owing part of that to me I've shot upwards of 500 rounds in the above rifles and more in 22 and a 357 carbine that I shoot very well its just a gray area not legal gun for big game here.

I've seen it forsale at an NAPA auto parts store.

Thought it was automotive in nature. Thanks. I'll give it a try.

So after using all of the hi tech Casey's Barns etc I found my Hoppes no.9. Brush patch repeat x3 now it's clean some more. The shiney spots at the muzzle are infact pitting. So a 1 inch cut and crown is the next order.

Stay tuned.
