Recommended neck turning gear

Post by Lorgar » 12 Mar 2014, 8:05 pm

I think it might be time to start turning my necks.

I'll be resizing and turning brass from .308 into 7mm-08 before turning the now 7mm brass.

Recommend me some neck turning gear, go!

K&M kit from BRT is what I use. Hard to beat. You can take the case holder out if the handle and put it in your vordless drill

I think Chronos means "Cordless Drill" and irrespective which equipment you might use ...Slow Speed. Really slow.

You need to use, again irrespective of brand, the associated "Mandrel" to expand the neck so that the fit / clearance is correct.

What is not pictured is the actual "Carbide Cutter".... It does a much neater job and if you are turning a lot it doesn't go blunt so quick.

Why is it time to start turning your case necks ..... ?????

It's probably a whole new subject but unless you are using "Bushing Dies" the neck turning doesn't work so well.

To answer your question.... the same answer as Chronos .... K&M Gear available from BRT.

No Apollo, my drill is completely vordless. LOL yes obviously a typo.

I think a light skim on necks can help give uniform neck tension even if using a factory chamber and " normal" dies

It also comes in handy if you like me neck down cases like my .308 to 7-08 lapua cases

Sorry mate, all in jest.

Yes, a very light skim. As you know I don't play with the calibres you do but for someone starting out the idea of "Neck Turning" I'd like to know the reasons why and the equipment available in order to provide better help.

Neck turn too much with a factory chamber and a normal die can result in too much neck clearance, leading too more blow back to the shoulder, not enough seal and carbon deposits in the chamber / neck area unless cleaned properly.

My bad. Perhaps I should not have added those comments but I would like the "Time to Neck Turn" to be explained and I was only trying to issue a caution.

Yeah mate I knew you were just kidding about my spelling. Damn fat fingers and tiny phone key pad :)

I also have the lyman mini lathe off trimming and neck turning but Like I said the k&m kit is the best unit I've used

I'm using Sinclair's neck turning gear and have been really happy with the results. There's a couple different kits but the one I went for was the NT1000 if I remember correctly (the main unit was green and it cost about $220)

As said above the most important thing is getting the mandrel that matches your neck turning unit and going really slow.

As to the comments above about not needing to neck turn with a factory barrel and dies, you should have a look at my thread on here about neck turning. When I started doing it I cut my groups by about a third. My groups with neck turned brass are consistently smaller than the same load but with non neckturned brass

What does the mandrel do exactly that a resizing die doesn't?

It over sizes the next so there is more pressure on the cutting bit or something does it?

Just neck sizing then turning doesn't work?

I'd say that the sizing die would leave the inside of the neck .005-.010" smaller than the caliber .300 for a .308 for example so that the neck grips the .308 bullet

You would need to have the neck the correct size so that the neck fits over the mandrel in the cutter

Thanks for the K&M links guys.

A few reasons...

1) I've recently switched from shooting .308 to 7mm-08 and have necked down all my old .308 brass. Having put a box of hand loads through it's clear the additional neck thickness is causing some sticking issues, difficult chambering etc. I know this will correct itself in time as the necks thin, but...

2) Something to learn.

3) Something to do.

Any of those will do as to "why".

Things like the mandrel are bits I need to research (early days on neck turning, still missing plenty of knowledge I'm sure). In the few YouTube videos I've watched they skipped this kind of stuff and just show themselves working the case in the turner and the excess brass peeling away.

The way the videos are shot (that I've seen anyway) suggest you just resize your necks and put them through the cutter/turner.

Any tips in addition to the right equipment are obviously welcome.

It's important to have the correct resizing mandrel that matches your neck turner mandrel so you have a tight fit for accurate and repeatable cutting depth

Another thing you'll need is a good tubing micrometer to measure the width of your case necks to determine how deep to set your cutting blade/ measure results. I use a Mitutoyo one which is good but if I was buying again I'd get a digital one instead because I find it hard to read small variations (under a thou)

Another important part of your case prep is to ensure all your brass is as close to the same length as you can otherwise you won't turn the full length of the neck on some cases and the unturned part can cause a donut inside the case neck upon firing which I've heard is a bitch to remove

This link has some good info and is the main resource I used to learn about neck turning

I bet this is turning into more of a pain in the ass than you were hoping for Lorgar :P

See you on the firing line.
