I have been assembling a Grendel from a 16" BCA barrel and bought an AA Overwatch in the meantime.

The Overwatch is precise enough with Wolf steel, Hornady SST and AMAX.

The 16" BCA barrel finally showed acceptable precision with AMAX factory ammo only.

Yesterday, I started resizing Grendel brass for the first time and noticed something strange.
Guess which brass was fired in the BCA barrel sidecharger and which in the Overwatch with brass deflector?

Finally, some dummy rounds with 85G Sierra bullets which I loaded into 6.5X55 in the 1980's.
I haven't decided on a powder to try for the Grendel.

Until my last time at the range with the BCA Grendel, I was firing rounds without a gas block and just mortaring out the rounds with the side charging handle. It was easy against a solid wood bench. What are the implications of the stripes? Should I contact BCA for a return or just keep this oddity? It operates fine in both manual mode and gas operated mode. Would a smoother chamber make it easier to manually eject a fired round? Does anyone here have any experience with this? I live in Pennsylvania which still does not allow deer hunting with semi-autos so it must be manually operated.
