So I have a Remington 700 7mm rem mag with factory barrel and action bedded and floated in a Manners EH6 . Whenever I run round rounds through my chamber it leaves these marks on my bullets. There are tick marks running vertically on the bullet and ring marks about 1/8" above the brass. Is this normal for 168 gr berger vld's? It is HSM ammo. It takes some force to close the bolt but it is like that with all of the different ammo I have tried. I've tried federal premium 160 Nosler Partitions, 162 gr hornady eldx's, federal premium 165 gr sierra gamekings, and the hsm 168 berger vlds. The VLDs definitely shoot the best with easily 1" groups or less and the worst was the hornady 162s which i could barely get to group 2". When I first got the gun it had to be shipped back to remingtion because all ammo would get stuck in the chamber and couldn't extract it. I don't remember exactly what they did to it. There is also some shavings of brass in the chamber which i think are from when i lock down the bolt. Is this normal or should I take it to a smith after hunting season? Thank you in advance for your time.
