Try to avoid using the drill attachment for the lapping tool and do it by hand. Sure it's slower but you can be far more precise in material removed. Takes about 10 min by hand.

That is a very kind offer. I just tore it down and posted a update what I found. I know after the next visit to the range if the barrel worth playing with. Crown was washed out. Poorly polished. I no longer have access to a lathe. Gave it to a buddy to recrown. His range rod went in deeper than he is a custom to. We did not slug the bore, the scope did not show any major faults. The feed ramps were denting the shoulders and causing severe bullet runout problems verified on my Sinclair Bullets runout gage . A bullet with .004 going in ejected with over .025. And dents and gouges that could interfere with the round sitting correctly in the chamber. A little reprofile and polishing solved that. Thanks for the kind offer, I may very well take you up on it.

Who made the barrel?

Classic Firearms reportedly sold rebranded BCA (Bear Creek Arsenal) barrels. There are numerous threads on various firearms forums regarding BCA 6.5 Grendel and other caliber barrels. To be polite BCA lacks consistent QC and has sold a lot of poor quality barrels.

I hope all the effort invested pays off.

I thought you said the range rod fit looser than normal?

See if Shaw is still making Grendel barrels. Or Lothar Walther. Shaws are hunting grade but at least they are dependable and are low in cost. Lothar Walthers are much better than Shaws but no Krieger by any means and the LW barrels used to be a very good value.

I have a LW barrel on a .223 Ar platform that I built about 10 years ago. after 1,000's and 1,000's of round out west shooting P. Dogs it still shoots 3/4 MOA 5 shot groups all day long. I just can not shoot it out!

May want to take a look at this barrel. It's on sale right now, won't break the bank.

The 16" was on sale when I got mine about 2 weeks ago. Used it to rebuild a pistol I blew up I'm getting very good results from it.

This is their 18" version.

Just something for you to think about.
