Help setting up neck turner please

[gcoulsey]

Hey chaps,

I have just recieved my k&m neck turning tool, mandrel and expandiron (.30 cal)
for uniforming my brass.

I have just about every other tool needed for case prep, but still feel different neck tensions when seating bullets, this bugs me, so even though I'm just using a blue printed remmy action, I thought I would try out some turning to even up neck tension.

(hope)

however, I have not recieved any setup/operation instructions, and was hoping someone could talk me through it briefly, or link me to some tutorial or something??

Again, I'm only interested in neck uniformity, not turning to fit a precise tight neck chamber.

My fired brass is slack on the mandrels, so do I run them thru a lee collet die first? I want to neck size with my Forster neck bushing die, but it has no expander to uniform the I.d ... I'm sitting here surrounded by tools, with a blank look on my face.
I know the easy option is to prep and load up my usual routine.. But having spent the money, I want to at least try this neck turning thing!!

Thanks in advance,
giles.

Here's what I do with fired brass. BTW, my stuff is all Sinclair's.

Full length size them first, or the collet die if it sizes all of the neck. Then I run them in the expander mandrel to equalize the fit on the turning mandrel. Good fit on the turning mandrel is mandatory for good results. Then neck turn. If it's a factory chamber, I wouldn't go for 100% clean up. 75% is plenty.

Can't help you on the K & M setup. My old Sinclair is a bitch to sneak up on the correct cut. That's why I got three of them. Two I leave set for my tight necked reamers, and the third floats for where it's needed next.

Ah no problem, I have pretty much got it working now.. And shining up about 3/4 of the neck as suggested.

Thankyou!!

A good set of auto-motive FEELER GAGES will get you real close to the desired neck thickness you want! Measure some of your neck and go from there! That's I how I set mine up! Most times I just go with a given thickness that I know my rifle likes.

Excuse the poor English and spelling! I am typing with the help of prescription med's. LOL Had a couple teeth pulled from my skull!

I only neck turn new brass. When i get new brass i run them threw my Foster full length no bushing die, with the expander ball. I also has the K&M neck turner with the carbide 4 flute neck pilot. Put a little case oil on the pilot and with the drill, start to slowly push the brass to start cutting. I don't use the expandiron mandrel. Just straight form the die. Only works with new brass. Generally i cut 95% to 100% of the neck just to clean up the case. You want to just start to cut into the shoulder witch helps so you don;t get the donut. This way has been working really good for me. He are some videos that helped me.

Re: Help setting up neck turner please

Thanks skyking, I wondered how far to the shoulder to go, sounds like I didn't take enough off.

I found I didn't need the expandiron die also, my brass had nicer snug fit on the
Pilot/mandrel after running thru the lee collet die.

I am suprised at the tiny bearing surface of the cutter on the brass.. I had always imagined it to be a broad (1/8") flat blade, engaging the brass like a wood plane!!
