Savage 110 FCP destroying brass. Pics inside.

[Jeff_C]

I have a Savage 100 FCP with HS precision stock in .300 WM.

The casings pictures are Federal Fusion cases.

These particular casings have been cycled through the action about 30 times to develop a damage pattern.

The action feels very stiff to operate, especially compared to my dad's Browning A bolt. There is almost a grinding noise and feel as the action works over top of the other casings in the magazine. The rounds don't feel as if they are chambering smoothly and the action feels rough.



Here you can see the damage. I have realized the marks around the mid section are from the DBM lips scratching the brass. What I am more concerned with the the multiple horizontal slits around the entire casing with no consistency. One in the middle is even visibly cut into the casing.



Here is another casing that has a very defined groove almost cut 1/3 of the way down the casing.



Here is a casing that was single loaded by hand and fired once. Even here you can see the mark 1/4 of the way down the casing.

Questions:
Is this normal for savage? Do they just have rough bolts and rough cycling with ammo?
What is causing these marks? Is there a fix I can do at home?
Has anyone else had similar problems?

Appreciate any insight. Thanks.
