Scoring inside case neck----cases now junk?

[Nickstradamus]

Searched the forum and net but could not find anything and wanted to turn to the forum.

During a recent trimming session for some 308 Hornaday match brass, I noticed an issue with my RCBS case trimmer scoring the inside of the case neck. I'm in the process if checking the pilot and bushing for alignment but I'm wondering if the brass is now junk? Running a screwdriver as a feeler down the neck you can feel the presence of the scratch. Pic below...thoughts appreciated.

Your brass is not junk but your trimmer is, my advice is to sell your trimmer and get a Wilson hand cranker, the Wilson is a micro lathe, I'm not a fan of any of the trimmers with pilots, scoring inside the neck will turn up on targets, where trim length will not(this ain't BR).

I swear, the most accurate ammo I ever loaded was back in the day with Lee press, Lee dies, Lyman trimmer... before I knew about bump gages and stainless media and concentricity.

Ignorance is bliss.

Polish the insides with a bore brush wound with 0000 steel wool rotated with a drill. You'll be fine.

I've always wondered about the scratch left by the pilot, but I've stopped worrying about it. I know that "everything matters" in a world of precision, but that's one that I can't see having much of an effect. The resistance created by that bur can't be a tiny fraction of the resistance that the bullet is going to hit .020" later when it hits the rifling.

Shoot the cases, see if you can still find the scoring.

And polish your pilots.....

I agree. I chuck my new pilots in the drill press and buff them with some Mother's mag polish. The line left behind in the case neck is probably more of a burnished line than a deep scratch.

Wilson....

Wilson....

Definitely a good option, but I sure like the 3-way cutter on the RCBS.

I appreciate the feedback. I'll probably try to clean them up a bit and shoot them as a mini science experiment and report back. I'll take a look at Wilson long term as well. Thanks!
