I just completed my first build and I put a full mag in and ejected a couple of unspent bullits.
The copper was gouged with scrape marks. Is this normal?
What effects would this have on the bullit's trajectory or barrel lining. The bullits were pretty messed up!

Could you take some pictures? Also, chamber a round slowly and eject it slowly - what's scraping against it? Locking lugs?

When you manually eject a live round out of the chamber, the ejector on the bolt will kick the right hand side of the bullet tip off the right hand lug in the barrel extension, which cause a long scrap down the bullet its self.

Also, until the rifle breaks in, there may be some burs at the end of the feed ramps that can scrap the bullet tips on loading.

Bottom line is that hand cycling out live ammo will produce scrap marks on the tips, and in regards to the feed ramp burs, in time they will be removed/polished out threw live fire/cleaning during break in.

I'll go out and blast away this weekend. I'll let you know what I find out. It's new so I imagine a break in period will resolve any problems.
