I've just bought a sako75 6ppc USA. Don't think I will need to neck turn. Looking forward to hearing your journey into the ppc world of accuracy
If you must I guess a K&M unit is a good start.
Lots of considerations as not clear what chamber you have or if the brass is factory Sako PPC or Lapua 220 Russian.

New Lapua 220 Russian Brass — Thicker Necks? « Daily Bulletin
Jackie Schmidt, posting on Benchrest Central, observed that there may have been some production changes with Lapua 220 Russian brass. This brass is commonly used as the parent case for fire-forming 6 PPC cases. The newer 220 Russian brass has slightly thicker neckwalls, and, according to Jackie...

I have some new 220 Russian Lapua brass which will need neck turning and some new Norma 6PPC which I understand is a no neck turning brass?
Grateful for all advice.
I used to neck turn .220 Russian cases for my 6mm PPC BR rifles because they had ‘tight neck chambers’ (0.262” or so) - this situation is typical for the vast majority of BR rifles.
Chambers with the standard necks (such as 6mm PPC USA) don’t need the cases turning.
With a .270” neck you’ll have to check the neck diameter of a dummy loaded round to determine if you have enough clearance without turning.
A so called ‘no turn’ neck in a BR rifle is normally around 0.272” to 0.274”. The 6mm PPC USA chamber will have at least this neck diameter, or slightly larger.
Be very careful - I suspect the 6mm PPC Norma cases you have are said to not require turning because they are intended to be used in the commercial 6mm PPC USA chamber. Do not use them in your 0.270” neck rifle without checking the neck diameter of a dummy loaded round.
There’s plenty of good information on neck turning technique in benchrest shooting related books such as ‘Extreme Rifle Accuracy’ by Mike Ratigan. Or forums such as benchrest.com
I strongly advise you to buy the Ratigan book or ‘The Book of Rifle Accuracy’ by Tony Boyer before you start on this journey.
For equipment, the turning tools by Sinclair (available from Brownells & 1967Spud, et al.) are excellent. You’ll need a very good micrometer & preferably an equally good tube micrometer. The books I’ve mentioned will cover the bits of equipment.
The procedure for good neck turning isn’t complicated but it has many subtleties - particularly in the context of competitive BR shooting. There’s too much to relate on a forum posting so read a good book on the subject.
One piece of advice I will give though is - the key to easy & consistent neck turning is getting the sizes of the expander mandrel & the turning mandrel correct (i.e. the correct relationship to each other). Sinclair sell the right combination.

Thank you for taking the time to respond so comprehensively. Much appreciated and will look for the sources however the Tony Boyer is like rocking horse manure to get hold of!
If you can’t get the Ratigan book I’ve got one, surplus to requirements.Thank you for taking the time to respond so comprehensively. Much appreciated and will look for the sources however the Tony Boyer is like rocking horse manure to get hold of!

Well somewhat embarrassingly all I can find is Dorothy Ratigan who seems to be prolific on knitting socks and another Ratigan on shipwrecks! Perhaps your spare book is up for rehoming after all?

The 75 is 6mmPPC USA which is a no neck turn chamber.
Having to turn necks is a PITA that unless done real well and all the other componets and the cutting of the chamber is built that way don't go there.
I don't miss turning necks !

Be prepared to 'sacrifice' a few cases in pursuit of the perfect cutter transition from neck to shoulder: You are being redirected...
Once you have a K&M mini lathe adjusted to where you want it, lock it and leave it. If you have other chamberings you need to neck turn, purchase additional cutting units.
There may be less fiddly cutters than the K&M, that make adjustment less stressful, but I'm not familiar with them so can't recommend an alternative.

I used to have a 20ppc, and reworked 220 Russian. That needed neck turning because the neck needed to be reduced, and this thickened the brass, but if using an expander to increase a 220, to 6mm/243, will it still need neck turning ?

Accuracy wise I’ve found the flat base bullets are most successful for me giving .3MOA or less
21st Century do some good neck turning kit.

Hi.
fwiw, i use K&M neck turning tools to make my .22BR from the 6BR parent case. I see Reloading Solutions have them. Prices have increased somewhat since i got mine way back.

This is the K+M Micro-Adjustable Case Neck Turner body (pilot not included.) Some reloaders like to have multiple tools set up and this is a great way to purchase an additional tool. Pilots available separately.
