Custom neck turners

You are not cutting but squeezing the necks causing it to flow into the shoulder?

Rich

Yes, but the squeeze flow also lengthens the necks. Not smart enough to understand the % of each.....or if any of this MAS on accuracy.

Correct, but with the squeeze method I make multiple in and out quick passes until the neck thickness is perfect. The brass flows into the shoulder and lengthens the neck.

More like a fine wine

I wonder if I could get my PMA tool to do this I have about 300 pieces of BR brass to turn

Let me get this straight. Your micrometer told you that you cut too much with brand A neck turner. You then ran the same brass that was previously turned with brand A through the K&M. When you measured the wall thickness after passing the brass through the K&M it was then greater than the previous reading?

Yeah. It was like magic.

Yeah. It was like magic.

Voodoo, just like pushing the brass to the shoulder without cutting it.

Material shape/thickness can be altered via cold working. What’s being described here would be a process akin to cold rolling. The tooling shown on K&M’s web site does not appear to be intended for this process, but I never discount anyone being ingenious! I hope that additional details are shared by those currently using the process... including K&M...

Would turning the neck backwards against the cutter do this?

It very well could!

OK, Dusty, you win...

As an aside, my K&M leaves me with this (rough cutting 300BO formed from 223):

Something I learned here-

Use the KM or whatever mandrel to set your inside diameter then use a feeler gauge to set your cutter at the right amount of cutting. Your necks SHOULD come out uniform.

My mantra of the month- wind and trigger pull, wind and trigger pull. The other stuff will drive me bonkers if I focus on the other stuff since no matter how precise one is with the 30 variables one encounters in hand loading, it still comes down to wind and trigger.

It may come down to wind and trigger but sometimes you have to turn necks to even load ammo

Trolling or dementia?

IMO, cutting necks is not as consistent as smushing necks.

WTH????? Are we being trolled?

 

[avidflyer]

someone call k&m and ask about this brass smasher.....how much? and if in stock?

 

[1911nut]

Ben is undoubtedly using a Pfluger centrifugal rotary cartridge neck swage.

 

[P1ZombieKiller]

Ooooohhhhhhh!!!!! I understand now!!!!!!

Did I do it right?

 

[BenPerfected]

More lube?

Here is something that I learned using my K&M. When the cutter gets dull, it cuts, but is also does something like metal spinning on a lathe. The dull cutter squeezes the metal down as it cuts so that the neck becomes longer. The cases grow in length quite a bit. Switching to a sharp cutter resolved the issue. This may relate to the fact that K&M's cutter has a negative rake angle, which is certainly appropriate to the job that it does, but which may have unanticipated consequences when it dulls.
