The Hornady set for full length sizing is what most people use. I have both the Lee and the Hornady. The Lee sizes the neck down too much then expands it back up and over works the neck which will cause premature neck cracking if you don't anneal often. Another way some go is to use Redding bushing sizing die. You can go over to the 6.5 Grendel forum and do some reading or just ask your questions and get some good information.

I have had very good results with Forster 6.5 Gr dies. Loading for 2 gas guns and a bolt action.

I use a Redding body die followed by a Lee Collet Neck sizer. I find that this method gives me the best concentricity.

Get the Lee factory crimp die if you're planning on crimping. A lot of the bullets you use in the Grendel won't have a cannelure and the Lee fcd will make it's own.

It is not necessary to crimp if you are getting proper neck tension. Go to the Grendel forum and join and do some reading on the subject. I have done it both ways and see no difference in accuracy or function except with one particular bullet. It was the Sierra 100 gr HP. It has a BIG HP and the nose is almost flat. I did not crimp them and they wanted to nose dive into the feed ramp and jam and it drove the bullet back into the cases some. I did not try them crimped because I was just trying to find something that would shoot good in that particular rife. When I built both of my Grendel's (long story of why I built two) I was looking for a bullet to deer hunt with and my time was limited to get that done with the trouble I had, (which is part of the long story). Once I got things right with the rifles I just worked with Hornady 123 SST, 120 Sierra Pro Hunter and 120 Speer Gold Dot. The 123 SST just would not shoot well in either of my rifles which have different barrel makes no matter what load combo I tried. They shoot sub MOA with the other two bullets and IMR 8208. At present I do use what I call a medium Lee Factory Crimp on my hunting ammo just because it makes me feel good. LOL If you are going to crimp do get the Lee Factory Crimp Die.

After doing some checking I think if I go with.003-.005 neck tension I won’t have to crimp. Was looking at the 3 piece Redding competition die set. I assume that I will have to keep my brass separate from my wife’s gun for reloading?

I have RCBS dies and they work good, but I'm sure the other brands work too. My only comment is that I crimp every thing I shoot I my ARs after seating the bullet.
I know a guy who blew up two 5.56 ARs within minutes of each other. The loads were safe recommended loads. The only thing we could figure out was the blow ups occurred after the initial shots. On the remaining rounds we could literally push the bullets into the case with hand pressure. We concluded that the bullet was pushed into the case as it fed from the magazine thus causing an over pressure.
