I have a brand new rifle in 6.5 creedmoor.

I'm shooting a mild hand load of 39 grains of H4350. This charge is right in the middle of the manufactures recommended max and min charge. So I don't believe it's an over pressure issue.

When I shoot a round, the bolt lifts easy but hard as can be to pull the bolt to the rear and eject the round. Once the round is ejected there is a scratch or gouge near the shoulder of the spent brass and sometimes a line or scratch running down the brass.

Is is this a chamber that has an edge that wasn't polished or am I not resizing the brass correctly?

Im using a Redding full length resizing die.

Only 20 rounds total through this rifle and every spent round is difficult. I can eject a round that hasn't been fired. No issues there.

Also Savage sent me a 4 round magazine that will not chamber a round from the magazine. It causes a double feed every time.

Any advice would be appreciated!
