Question about Neck Turning

[Webster]

I have a question about what procedures are desirable in connection with neck turning. I've read a number of different opinions on this and am not sure just how to proceed. I'm handloading a .270 Win. and thought I'd try neck turning for the first time. I had thought that I'd run my new Norma brass through my FL sizing die and then turn them. I'm assuming that the expanding ball will open the case neck up to the right diameter for my turner mandrel. The Sinclair mandrel mics .2755".

Is this plan adequate, or are there other things I should consider?

You should get an expanding mandrell with your turner. I would first try removing the ball expander from the FL die, expand with the mandrel that comes with the turner. I like that your using a FL sizing die since it sizes the full length of the neck. Bushing dies only size half of the neck. You want a snug fit with plenty of lube. The case should slide along the turner mandrel with very little if any side wiggle. It's a hunting rifle why do you think you have to turn the necks. It would be a miracle if you see a difference in accuracy.

One thing I've just noticed: After neck sizing with a Redding die (not the bushing version), my Sinclair turning mandrel can be inserted into the necks. The fit is snug, but not overly tight. I can turn cases on the mandrel without excessive effort. I'm thinking that I may not actually need the expander mandrel step.

That’s really all that it comes down to. Lubricate, go slowly, and for a hunting cartridge id aim for 80-90% cleanup.

Feel free to test turned vs unturned brass. May show a difference, may not.

I made one phone call to Pat at PMA tools he hooked me up with everything I needed and had it to my door in just a couple days.

How much for the set up.

K & M makes mandrels that are sized correctly for expanding necks for turning.

K&M turning equipment can't be beat.

Both turning and expanding mandrel fit the same holder for Sinclair.
