Cleaning inside case necks??

Big Ed, is that a Savage Enfield?

How clean does the inside of the necks need to be when annealing? I have always heard if anything was left in the inside of the necks when annealing, it would burn in. Or what is your process cleaning brass, inside and out before annealing.

I use birchwood casey case cleaner.It cleans the case inside and out rather nicely. Its good stuff made for the purpose of cleaning brass. It removes the soot and any lube used for resizing inside and outside.

I recently bought an ultrasonic case cleaner. When the inside of the necks started coming out as clean as the outside it concerns me a lot. I am thinking about using graphite neck lube to treat my cases before seating bullets.

I would appreciate any feedback from all ya'll.

I have done a lot of testing and find it makes no difference...Same as primer pockets.

Anyone using a progressive press does not do all that cleaning..Like weighing ever

powder charge..No need to do it..
