Brass shavings when resizing

[Blaktastic]

Well I am pretty new to reloading and I just got my FL sizing die dialed in. My only issue is that on the downstroke it stops about 1/3 of the way down and I have to force the case out of the die. This results in small brass shavings coming off of the neck. I'm not sure if lubing is the problem or not but I am not lubing the neck at all because I was instructed to only lube the case body. Any help to why this would be happening would be awesome.

Video of this happening below.

blacktastic thats the button coming back through the neck, are they bushing dies?? if you lube the inside of the neck with a brush and dry lube , the expander button will slide through eaisier

Or get bushing dies for about .002-.003 tention and shit can the expander button.

^^^ This. The big thing is that it has the resistance 1/3 or the way down. That is the position of the expander. You could try a little lube on the inside of the neck and see what happens or just test it out with the expander removed

remove your expander and try again. Sometimes my expander would snag on the case.

Lube inside of neck. You're going hard on it.

Ditto lube your neck, but also pull your expander ball out, inspect for brass galled to it, and clean with scotch brite or equivalent if you find it there. Once brass sticks to your expander ball, it will "plow" a furrow in every neck that passes over it. Your call, but I tossed the lot of brass I learned this on due to the significant grooves cut up the ID of the necks. School of hard knocks. . .

Re: Brass shavings when resizing

clean your brass first and be very conservative with lube in the necks, make sure to remove all the leftover.
hope this helps.

Re: Brass shavings when resizing

I've 86'd the expander ball on all my sizing dies. Neck or full length sizing, no expander. I finish all cases with a Sinclair Expander Die using the Oversized mandrel. All cases come out with nice straight necks and .002" neck tension. For lube I merely use a Forster "Graphiter" with dry lube.

Sure, it's an extra step but the results are a lot straighter finished case with less run-out on the finished round. Only exception to the above process is when I use a Lee Collet Die which produces the straightest cases of all. Just doesn't bump the shoulder which can lead to some difficulty in chambering rounds.

If you're going to keep the expander ball in your sizing die, do this: disassemble the die, and chuck the decapping stem/expander ball in your cordless drill. Spin it and polish (emphasis on <span style="font-style: italic">polish</span>) the expander ball with progressively finer sandpaper, on up to 600-800 grit. All you want to do is polish it, not make it smaller. If the ends of the expander ball are blunt, you may want to round them slightly. Hose the assembly down good with brake cleaner or gun scrubber, then reassemble.

Lube your case necks, and you'll notice that things go <span style="font-style: italic">so much easier</span> now. The best 10 minutes you can spend with a sizing die!
