I often read of people lubing the inside of case necks before bullet seating. Personally I have never done this, instead after preparing the case I finish with one in/out pass with a PB brush in a cordless drill.

So does anyone lube the inside of case necks?

Not exactly lube the case neck but I do lube the bullet before seating with a little Boron Nitride powder - very slippy stuff.

Are you just lubing or actually coating the bullets? We moly coat for Christel's 22-6.6x47 and I have often considered Boron Nitride as a cleaner alternative but never been able to source it at a sensible price.

I just lube the bullet with a a bit of powder on my fingers - I picked up a small bag of BN with a view to bullet coating in the tumbler to try and extend the barrel life of my 6.5x284, I've just not got round to actually trying it yet.
It's certainly nicer to use than Moly and a litle goes a long way - It would be "group buy" project.

Never specifically lubes the inside of the necks, but started using Lyman spray lube a few years ago, so I suppose I now inadvertently do...

Can't say I can tell the difference from when I didn't.

If I am using dies with expander balls then I dip the case necks in Reddings graphite coated ceramic ball media... comes in a tidy little jar and lasts forever.

It does entail a minor cleanup of the graphite which clings to the outside of the neck but that is soon removed with kitchen paper and I am hoping to reduce any 'drag' as the expander comes up through the neck...... reduces chances of expander-induced donuts and helps concentricity.

I also dip the base of my bullets in the same media before seating.

Couldn't say how much it helps but don't think it can hurt anything!

It was prepping brass this morning for the 6,5-284 that made me think of it. A group buy sounds like a plan, now all we have to do is find some minority moly coaters who want to try the BN.

I lube the inside of the neck when I resize, but not specifically just before I seat the bullet.

I would be interested in the 'Group Buy' thing but don't have a clue where to actually buy it.

We need to be careful that its HEXAGONAL BN ... I believe there are two types? There is an article somewhere in the Accurate Shooter website on this issue.

Inside neck should be lubed for resizing with the point off cleaning it off afterwards is ensure CONSISTENT neck tension on the bullet.

Having some or a little lube on inside or even adding more creates a variable that cannot contribute to consistency

Read the manuals and they specifically state it should not be lubricated
