Help with loading 6PPC

[beltfed]

As with most pet projects, after close to a year with my new-to-me Sako 85 Varmint in 6 PPC, I've just gathered all that I need to begin loading up for this rifle.
I've got a small supply of mixed brass which is the following:
- already fire-formed 22PPC, Sako (approx. 100)
- already fire-formed 220 Russian , Lapua (approx. 100)
- new, yet to be fired 6PPC USA, Norma (approx. 50)
- and finally two boxes of new Lapua 220 Russian that I've yet to mangle.

Q1 - I've gone ahead and run a number of the new 220 brass through my Redding 6ppc FL sizer with the help of some Imperial sizing wax - Seems simple enough...Is there any reason not to do the rest like this? ( I've been on 6mmBR.com and don't have a separate fire forming barrel, so some of the suggestions on there are not practical).
Also, while neck sizing some of the once fired, I've noticed the de-capping pins are too large for the flash holes. Is this common? Does Redding make a special de-capping pin to work with this brass?
Q2 - Any tips on blowing the shoulder out for fire- forming? Anything to avoid?
Q3 - Let's hear some favorite recipes for this cartridge!

Cheers!

I don't know about the fire forming part but I shoot a 6BR and the Lapua brass I have has a smaller flash hole and yes my Redding dies have a smaller decapping pin. My understanding is that if you contact Redding they will send you the correct one and I think for free.

Or just go buy an RCBS or Redding de-priming die. They're cheap and it lets you clean or tumble brass before you resize. I've pulled the de-priming pins out of all my dies.

I find it a little odd that Redding wouldn't include the right decapping pins with their 6PPC dies in the first place.
Both the FL and neck sizes have the same pin sizes...

Flash holes on 6mm PPC brass are slightly smaller than standard, so this would not help.

For the OP, the go-to powder is H322, 27.7-28.2 grains with a 68gr Berger. N133 is also popular.

Regarding the powder weight I just listed... use at your own peril, it's a range designed for a robust benchrest-specific action with Lapua brass. Find a tested load in a book to compare to and work up as usual.
