What's causing scratches along the bottom case length?

My Rem 700 action is causing deep scratch marks along the bottom base rim and up the bottom case side of my new Lapua Tac 20 brass. I remember a thread not too long ago in which somebody described the same problem, and someone else here explained what causes it and how to eliminate it. Lo and behold....I didn't realize I'd have the same problem or I woulda studied up on it.

I'd appreciate it I could be instructed what part it is in my action causing this and what I need to file or polish to eliminate it.
 
If you have a factory ejector spring clip some from the length to lessen the tension so it does not scrape the case as severely when it's being extracted. That is likely what is scratching the cases. Sometimes it will put a ding in the neck as well.
 
I had already lessened the pressure of the ejector before using the rifle at the firing range so that the case is only tossed out a few inches.

I could be wrong but I thought that perhaps this deep scratching was occurring at the very bottom of the case. (?)
 
You said it was a Remington 700 so I'm going to assume your using the magazine. The rails in the action will leave a mark on the case, much as you describe. Polish the lower inside edge and it should help.

Yes, I sure am. I'm popping one round down into the top of the magazine before I push it forward with the bolt and into the chamber.

I need to go grab my rifle and study the magazine area of the action.... but I assume I will see some sharp edges that you are referring to.
 
You don't metion what model you have but I've seen this a lot, especially on the low cost 700's. Remington just doesn't take the time to polish up the metal work on their low end guns. As mentioned earlier, it's more than likely the rails on the magazine. Take some 400 wet/dry sandpaper, rub some light weight oil on it and smooth up those sharp edges. You'll be able to feel with your finger tips how rough they are. Just go over them lightly until they feel smooth. Than test your cases to make sure you've solved the problem.
