Thoughts on how to remove scratches from inside neck...

[22DASHER]

One of my trimmer mandrels scratched the crap out of the inside of my necks on some of my Dasher casings. Any ideas on removing the scratches!?!?... I really don't want to ream them out...

Steel wool 4/0 wrapped around a 22 cal brush. It will at least smooth them out and don't go crazy. Chuck the brush in a cordless drill.

I was afraid that was the only option

You can get a carbide expander ball from Redding. Use it to burnish the necks. The carbide ball will iron out any raised metal.
Then load and shoot.

My advise:

After trimming & chamfer (I also do it when there new, after expanding & chamfer).

My 21st century turning mandrel will mar the insides of the neck if I don't use any lube. I used 4/0 steel wool wrapped around a small diameter Allen wrench to clean them up.

I use a Giraud trimmer and my Forster classic collects dust.
