Where to buy Lapua 6PPC no-turn neck?

Pretty simple - Buy the brass. Load it and shoot it in your rifle.

You could always buy Norma 6PPC brass if you don't want to mess around with extra steps.

Sounds like a great option, thanks.
For the other questions:
- I'm using this in a Sako A1 6PPC-USA.
- I don't have stuff for expanding or fireforming. My neck sizing die is a Lee collet type.
- I have some Sako brass, can easily buy Norma, and I'm simply curious to try some Lapua. 100pcs is plenty.

For what you are doing, I wouldn't even bother with the Lapua Brass unless you are interested in paying a premium for prepped brass that IMO will give you no better results than buying a box of Norma and being done with it. YMMV
He does a great job he has done some for me you won't go wrong with DJ give him a call.
DJ,
Any consideration at all to stock PPC brass at some point to avoid the additional back and forth ?
Yes he does Bob.

I have thought about it and I would have to collect sales tax and submit the sales tax to the state. Too big of a hassle for such low volume.

Just an FYI regarding the use of Lapua .220 Russian brass necked up to caliber 6mm with NO neck turn for use in a factory Sako 6mmPPC chamber. It won't work, I tried. The factory Sako chamber has a Ø.271" neck. A loaded Lapua case with no neck turn would measure about Ø.272" using the old Lapua brass (.0142+.0142+.2436) or about Ø.2736 using the newer Lapua brass (.015+.015+.2436).
For what it's worth, you have received some good advice with the suggestion of trying Norma 6mmPPC brass. I use Norma brass straight out of the box in my Sako 6mmPPC chambers and it works great. I have 3 Sako A1 single shots with the holes in the trigger guard and 1 Sako Deluxe 6mmPPC repeater all with the same chamber. In my experience, the neck diameter of a typical loaded round using Norma brass will measure about Ø.2655"
I also use Norma brass in my Panda with @ Ø.269" chamber. But you have to be careful when fire forming Norma 6PPC brass in a typical 6PPC match chamber as the headspace (shoulder) is about .009" short. In this case (pun intended), seat the bullet LONG for at least .01" to .015" jam to make sure the case is in contact with the bolt face and that the firing pin does not push the case forward off the bolt face when firing. If this happens, the case stretch occurs in the wrong and worst possible area, the web (near the base)...and that's a NO-NO.

Good feedback, thanks. I thought I had checked the neck thickness specs but clearly I did not get that correct. So if I buy some Lapua I’ll need to include a bit of neck turn in the preparation. Definitely kicks the difficulty of that option up a level.
That said, if the chamber is .272 and both Sako and Norma brass are .011 neck thickness, then using Lapua would permit a much closer fit to the chamber if everything is adjusted correctly.

Here's my 2 cents on the matter when answering your question in the second paragraph. Using a much closer fit (loaded neck diameter to chamber diameter) is not required or necessary. Yes, the clearance is on the large side @ .0025" per side neck clearance, but in my experience the brass is not suffering nor has it work hardened to the point where I can tell a difference in neck tension when sizing or seating, or where it prints on paper. Too tight a chamber is far worse that a little extra clearance from an accuracy standpoint.
The sole reason for One to choose Lapua brass over Norma brass is longer brass life when subjected to the HOT loads and resulting elevated pressures used by most competitors employing a dedicated Benchrest action. I do not think that this longer brass life benefit will be realized in your situation. I say this because the loads you will most likely be using will not be in the upper pressure ranges, as the diminutive and comparatively delicate Sako action will not take the abuse. If you have ever compared the bolt lug surface area on the Sako A1 next to a Benchrest action (Panda, Bat, Borden etc...) I think you might agree that it is not in the same category. The Norma brass used with Normal loads will hold up well and serve you well for a LONG time. For what is to be gained, it's just not worth tooling up for Lapua brass or paying someone to turn it for you when using the Sako.

But...if ya just gotta try the prepped Lapua brass, give Ron Hoehn a call and tell him the neck thickness you want. Order minimum is 100 pcs. I believe it all shakes out to be around $210 when all is said and done. I'm sure others offer brass prep services, but Ron's turnaround is pretty snappy in my experience.

You are correct with everything you said I have done the exact same thing

Here's a testament to the neck wall consistency on the Norma 6 PPC brass.
After reading this thread, I went and randomly grabbed a piece of brand new untouched Norma 6 PPC brass from my bin. Ran the neck in a 21st Century Shooting expander mandrel. Measured neck wall thickness at .011", then seated a Berger 105gr VLD target bullet after measuring the bullet for consistency. Took loaded round neck OD measurements at all points while spinning the case in the mic multiple times. Low measurement was .26510" and high was .26540". That's only a variance of .0003" (including the bullet). These necks are completely untouched from the factory. Oustanding neck wall consistency from Norma.
