inside neck with carbon

[FTRinTexas]

I clean my brass using the SS method. The last match I dripped the bottom portion of the bullet in a small container with graphite in hopes of smoothing out the bullet/brass release. The neck tension with bushing is .003”.
Question: does anyone make a nylon brass that is coated with carbon? Stick this brush in a power drill and start coating. It would have to be cleaner than messing with graphite.

Have you looked at the Forster case neck lubricator? While not carbon it still uses powdered mica.

I personally use the RCBS dry neck lube kit but I dip the brass in it. Not very messy with the exception of a couple of the ceramic balls coming out on occasion. I put the neck lube container in a lid from a empty margarine container to keep from losing anything.

If you want them to go in easier after stainless pin cleaning, here is what I do. I took a retired brush that I washed in brakekleen and then wrapped it in a small amount of 3 ought steel wool. I chuck it up in a drill and run it in and out of the neck and it causes the wool to bunch up alittle and deburrs(polishes) the top of the neck as well as the inside of the neck. It is sorta like honing a engine bore. The light scratches actually make it easy to seat a bullet.

I've always held the notion that if we didn't create the carbon layer with firing, someone would eventually market it to us!

IMO, it's perfect and should never be removed.

I am in COMPLETE agreement here! I use a VERY "used / carboned up" neck brush and brush my necks with it. It helps make that bullet slide right in with minimal resistance.

I think I know where this is going. I need more info before commenting: Why so much neck tension (.003)? Are you experiencing unusual resistance when seating bullets that you are resorting to lubrication? Are you annealing after tumbling?

+2.........and brush those necks right after firing while the carbon is still soft.

Do you guys clean cases at all, besides brushing inside of necks?

 

[ShootDots]

IF I anneal, I will clean my cases.. If not, I do not. However, having said that, the INSTANT I fire and eject the spent case, I use Krazy Kloth and wipe the carbon OFF the outside of my necks. Let that carbon get hard and build up and you can and will score the die or bushing. BUT, I do like to get "soft" carbon on the inside. Ergo, I have "old / carboned up" brushes that I run into the case neck. This facilitates the seating of the bullet.

^^^^^Reloading manuals since the '60's have advocated brushing the inside case neck with a nylon brush.....and my latest purchased manuals still do. Benchrest shooters (shortrange) have been using this method since the first organized matches in the '40's. Where did the idea that cases ( especially necks) must be squeaky clean come from? This is an area where reloaders tend to overthink the process and stray from a proven method.

You wrote: Benchrest shooters (shortrange). Any reason to think that this does not work for long range?

Only because I have never shot LR (> 500 yds) either in practice or competition. I will offer that one of my mentors has transitioned back to LR ( after garnering considerable points in shortrange BR) and continues to believe in leaving the carbon in the necks (after nylon brushing), and is doing very well in the LR game.

Any reason to believe that carbon buildup in the cases will affect load tuning?

 

[LHSmith]

^^^^^ You mean reduction of internal capacity? Considering most successful competition shooters load at or near the high node at which normal problem free case life is ~10 firings or less ...... then the answer is No, the volume differential would be negligible, and results on target prove this. Most top competitors have long since come to the same conclusion.........brass is expendable.

First post, long time lurker, long time shooter, long time reloader, many rifle builds, and new to F Class TR and Bench Rest.

Leaving carbon in the neck after firing is anathema to what I have learned in general rifle reloading for milsurp, hunting and general use. I brush it out with a new brass bore brush in my cordless drill before tumbling in crushed walnut. I tumble clean enough to ease FL sizing making sure no carbon is visible on the outside of the case.

But it seems like many like to leave it in, or add it after cleaning. Your posts don't go into detail. Please explain your methods in detail from extracting the spent case to reloading (in reference to the carbon in the fired case).

I am truly baffled on the inside the fired case neck cleaning procedures. Do you remove all the carbon, or just the loose carbon by brushing it out lightly?

All the case’s exterior straight out the chamber gets wiped clean as a Crazy-Kloth will. The neck gets a few licks using a Sinclair nylon inside-the-neck brush. I’m going after any crunchies and the loose stuff before it has opportunity to harden and/or grab on with a better grip. None of it is about 'pretty', don’t care.

I stopped using my SS tumbler for batch to batch cleaning. I've switched to a bullets.com ultrasonic cleaner because the necks were coming out too clean and I had to do some clean-up work on the necks (re-chamfer). I'm thinking about re-visiting this though.

The thread began with stainless pin cleaning. That is, total removal of carbon inside cases. A pretty good example of reloaders taking a basic step(brass cleaning) to an irrational level, and creating issues, while solving none.

I follow ShootDots and OleFreak. Same deal, no problems to solve in it.

For my F Class TR 308 loads I use Lapua brass and every third loading cases get stainless steel pin cleaned, and annealed. I will be using a just purchased Whidden non-bushing FL die for a no turn 1:10 Shilen.

I will continue the third firing annealing as I get it done local by a buddy.

Newly cleaned loads get sized with the Whidden die and loaded night before match, second and third will have necks brushed and bodies wiped of carbon at the range after firing and light tumbled as needed before being stored for loading.

I will experiment with the Whidden against the Lee neck sized loads that set a pretty high bar to cross. Whichever proves the most accurate will be the road I take. If they turn out to be equally accurate I will go with the one that takes the least effort.

Thanks for the input.
