Thread: Neck turning

He neck turned far too much, not paying enough attention to a lil silver barrel and white face poking out from behind a manuka bush

What is a good set up to get? Brand, good price etc? I don't even know what bits I need. 7RM and 308

@Gibo just want to ask why you wish to neck turn? Don't get me wrong, I am well into neck turning, but don't see such a need for hunting reloading. The brass I do neck turn however is all then sized using bushing dies to give correct neck tension. I am shooting tight neck chambers so turning is required to a degree. If using standard dies you can end up with not optimum neck tension or even worse if you turn too much off you end up in no mans land with std dies - unable to size down enough for the expander ball to do its job. BTW I use K&M. Upgraded recently to a carbide cutter and the difference in cutting and finish is amazing. I use the lightest viscosity cutting lube oil available. Wax can give inconsistent neck thickness results 1/4 up to 1/2 thou variations. I originally bought some K&M stuff off Sinclair but hardly use them now for anything - they are shipping rip off merchants. Ended up buying the bulk of what I have direct from K&M. For additional bits I now buy from Julian, if in a hurry or BRT in Oz for cheaper price but slightly longer delivery. There are slightly superior turning devices available eg little pumpkin but they are a lot more expensive than K&M. The only negative with K&M is the cutter angle is a standard dimension and doesn't cut exactly as I wish on my AI stuff.

He wants to neck turn because he has nothing else to do. His cook mows the lawns while he is drinking beer.

Neck turning is only complimented by annealing Gibo.

You are slowly going to be dragged deeper and deeper into the pit. 😆

I was picking up a little gas plant on my way home......yes I am sinking into the pit at an alarming rate

I don't really think its relevant as to why or why you shouldn't, if you want to, then do it.. but just make sure you understand the benefits/downsides so it doesn't end up in a bad experience

And those benefits and downsides are......

Yeah that may help me My thinking was consistent neck tension but in reality I don't know that I'd notice any difference

You shoot rifles well.
I've seen you shoot bug holes.
Your guns are hunting rifles.
You will notice no difference in what your doing/want.
Except more time in the garage.
Good Redding dies with correct size bushing =job done.

Party pooper

If you are going to neck turn for standard chamber in a hunting rifle, just clean out the outside of your brass. Even if there are a few small spots left unturned on the neck that does not matter too much. As said precedently, you will be better off with Redding neck bushing dies if possible. K&M is how I rock n roll as well.

What do you consider a tight neck please ? A chamber 0.002" over the loaded brass neck OD?
And how many thou larger in diameter would a reamer need to be across the neck for you to consider it as producing a "no- turn" chamber? I'd appreciate opinions on this as looking at reamer dimensions for the next project at the moment with a view to avoiding neck turning if possible.

If you end up with Forster gear then be prepared to find the mandrels are quite undersized. They advertise 0.002 - 0.0025" under but I have a 7mm mandrel here that measures 0.2805". The issue is that the brass needs to necked down to be a tight fit on the mandrel prior to turning. I don't reckon Forster have got this quite right because this level of undersize may be smaller than most unmodified expander balls will produce. Turning on a loose fit will likely degrade concentricity rather than improved it. The same for using bushing dies for this step where a bushing size may need to be purchased specifically to take the necks down to be a snug fit on the mandrel.

Puffin, I understand your concern.
Here is how I see it to answer your question:
Either you are shooting super accurate rifle with tight custom chamber, on bench rest ,and then going with something else than top quality brass like lapua is a false economy. That lapua brass will be already very good in neck concentricity, thickness and tension. So the neck turning you will do on it will just make it perfect. And the small irregularities will deseapear after the neck turning.

Or you are shooting a hunting rifle ( custom or not) but with a standard chamber : if you buy good quality brass for it then you do not need to neck turn, or you have a more average brass and then you could see an improvement and a justification for turning that brass to make it more consistent.

I turn my brass for my bench rest rig (30 BR), used to for my 6.5 creedmoor when I was necking down from 308 brass, now good factory brass is available from Norma.And I necked turn a small batch of 300 whisper and 308 for my subsonic reloading, and see better consistency on target.

@Gibo If you want to have sleepless nights over reloading & really fall into the dark side, buy a concentricity gauge

Mates got one�� Havnt used it in a while. Yeah im better of to get better at shooting to be fair. My reloads are better than i can shoot
