I got a hornady 6mm ppc die set and a 65 grendel redding S die with a 268 bushing.
Half inch groups are the norm using 107 sierra match kings over 31 grains CFE.
27.5 grains H-4895 shoot the same.
Tke 107SMK's have a BC of .530.
They will stay super-sonic to 1200 yards.

Took mine out for the first time today. I tried to use my Redding bushing die with the bushing that I use for my 6 Creedmoor and it did not reach down all the way to the shoulder so I bought 6ppc dies. Out of the 80 rounds that I loaded I could only get 5 to chamber. Those five were from three different powder weights but still shot and insane group for the first shots from a gun that hasn't been tested. I am just going to break down and try to find the reamer spec for my Barrel to get some dies made.

All you need is a 6.5 G bushing full length size die. Use a 268 bushing on Lapua brass. This works better than 6ppc dies as you get all the way to the base. Take a shoulder measurement with a Hdy comparator or similar tool and bump the shoulder about 3 or 4 thou and they will chamber.

In fact with that bushing die you can bump your loaded ammo so you don't have to break it down. Just take all the guts out, lube and resize.

I'm using a Forster Coax press, even with the die bottomed all of the way out on the plate, it would not size the entire neck. Pretty common problem with the coax.
With that said, all 5 shots could have been covered by a dime and I got pretty good velocity with the 105RDF.

So you can't resize 6.5 Grendel brass on a coax? Or any brass really as most of the time the die is close to touching or touching the shell holder on a normal press.

 What die do you have?

Sizing the neck from .265 (after firing) to .2638 is a lot different than .264 to .2428 though, hence the results above. I'm using the same Redding bushing die that I've been using for my 6.5 with bushings I use for my 6 creed. I have a full length die for the Creedmoor so I use that for my initial conversion from 6.5 to 6 but only used the bushing die after that.
Regarding the Forster, I'm not the only one running into this exact issue. I am not totally sure if it would be just as easy for me to mill the Locking Jaws on the press to allow the die to go down further. An extra set of jaws cost about 1/10 of what a new set of dies cost.

I guess I've never been around a coax press but I shoot a 6AR or 243LBC, whatever you want to call it. Formed  250 cases I think so far with a Redding 6.5G bushing die. Never had an issue but I use an old Ammomaster progressive or a RC. You are a long way from fully sizing that case it looks like unless you are leaving the bushing float a lot. 

Maybe switch to normal shellholders? Isn't there a conversion for that?

Arp is having dies made for his 6mm predator made from the Grendel case not sure how far out the time frame is

As far as float, I thought of that immediately, then I bottomed out the screw, same results. I tried it on my Lyman press, no issues but I just don't want to use it.
There is a conversion but I'd rather solve a problem that work around it. Also, if Forster made a $%&*&%# bushing die for Grendel it wouldn't be an issue. If you look at the base of their die, it's tapered match their shellplate exactly.
Even though I am frustrated with my first time out, it is obvious that this gun is a flat-out damn performer. That is why I am even more motivated to just go ahead and drop a little more cash to squeeze every bit out of it that I possibly can.

That would be awesome, and patience is a virtue but not one that I possess most of the time.

It's a heck of a round, IMO what the Grendel should have been. Just such a versatile diameter and lots of bullet choices.

So it sounds like the Redding die is full diameter all the way to the bottom while Forsters are reduced down at the bottom to match their shellplate? Maybe the bottom of the Redding could be turned to match somehow?

I hear that!
With the bullets available it will work on small varmints, yotes, deer, hogs and long range paper.
