Why is it that most ppc shooters choose to FLS there brass instead of just neck sizing it? I have my very first 6ppc on the way. I am completely new to the ppc world and i am trying to learn as much as possible. Everyone i talk to say to buy a fls die. I believe them, but why wouldnt you want to just neck size? Thanks Lee

With components used today, (mostly the powders and Brass), Benchrest Shooters have discovered that the extreme accuracy, as defined by "agging capability", is found at pressures that are a tad above what the rest of the planet considers normal. Even a load pushing a typical 68 grn bullet at "only" a flat 3000 fps is pretty far up in pressure.
Blame this on Lapua. Way back when there was no such thing as the "Lapua" factor, cases simply would not take the extreme pressures that Benchrest Shooters now dable in. But that little 220 Russian changed a lot of things. I have always said that if you took the Lapua 220 Russian away from us, we would all have to start all over in the way we approach this game.
So, to aid in feeding and extraction, (very important when trying to take full advantage of a favorible condition), the majority of shooters start with the Lapua 220 Russian and full length size from the very start. Forget that old stuff about neck sizing only being more accurate. A properly full length sizing can be just as accurate.
There is also the thing of brass life. Even with mild loads, even the Lapua cases will start to get sticky in short order if you just neck size only. Full length sizing allows you to shoot the Lapua case multitudes of times.
Go on ahead and get a proper full length die, learn to use it, and don't look back...........jackie

Jackie is talking custom based on your reamer and not a Redding or RCBS.

With hot loads, the shoulder needs bumping back to avoid closing hard.

...and the base of the case will get tight as well...so FL sizing with a properly fitted die is the way to go. Harrell's is a popular brand.

I have a JLC and like it a lot.
The gentleman that i am buying the rifle from says i need a small base fl sizing die. Does the small base mean i need something a bit different or is the small base ppc die common? I guess i need to send some of the fire brass to Harrels so he can make or match a die for me. Is this correct? Thanks Lee

The Harrells, Jim Carstensen, a couple of others do the same sort of thing. Based on cases fired in your chamber, they tailor a die to the, more or less, exact resizing that is needed.
Here is an article that explains:

Lee, you got it. Send 4 pieces of brass. A short note. Once fired is fine.
Better yet. Call the Harrell's. Real nice people.
These dies use a bushing, also. Redding or Wilson. Redding has a "TIN" coated bushing. Get .259", .258", or .257". Some guys like .257". I started with .259" and went to .258". At around 15-16 reloads.

I'll disagree with Zippy a little 
I do not believe that once fired is enough, in fact I send brass which has been hammered into shape with enough firings that it's getting tight on all dimensions...... more like 4-6 firings, @ 3250-3300 for the PPC.
This has worked well for me when ordering Harrell's and Neil Jones dies. I include a note which explains the fit. Something like "these have been fired 6 times and I'm getting a fairly solid feel on closing the bolt. Solid thumb pressure with freshly greased lugs."
I'm not convinced that once-fired brass is fully popped out. I fireform HOT compared to the recommendation of the reloading manuals and the fired case just falls out in my hand. And reinserts with no feel at all.
BTW I do this with all sorts of cartridges other than the PPC, shoot them out of the book that is...... with proper support. Winchester brass works almost as well as Lapua in this regard.

Hi Al,
I talked to Lynwood. I think, that is his name. Anyway nice guy. Had a new barrel. Was running out of time for the Super Shoot. He said okay.
This was my first year shooting Reg. Benchrest. My first Super Shoot. I am hooked.
This is a great sport. Something I can grow old with.
And there are a lot of opinions.
But, You have to start with some kinda die.......
Yea. Greased lugs!!!!!!
And I agree with you, Al.
5-6 firings and the edges start to come out.
I got a set. 18-19 firings. Nice and firm going in. Still shoot good.
