do i see a 223 grendel?

[sneaky one]

Bill. come clean., 20 cal. ??

[Longshot_34]

heh heh heh

[LRRPF52]

From left to right...

6.5 Grendel....6mm AR.... .224 AR...... .20 Grendel

My guess...

Guys, it's only been a year since the meet and shoot in Washington. Bill A. suggested a project back then and we're almost there!

Check back in about three weeks -- with any luck Pac-Nor will have delivered a barrel cut with a Manson reamer, cases will have gone through the Hornady dies, and we will have the first shots starting with Berger bullets!

It is a bolt gun, but the loads we plan to look at will cover the AR pressures too.

Think of a Grendel-based cartridge that has less drift than the .308 at 1000 yards and the recoil of a .223 Remington.

I wouldnt really want the smaller bullet anyways. Kewl project but ill stick with the 6.5mm

[GregP42]

OK, now you have me interested, but I am always up for something different!

[txgunner00]

Tease!

[JASmith]

Guilty!

Truth is things are kind of swamped right now. I will try to get a better description out before the three weeks are up, but the cans of worms, swamp draining, and figurative alligators are kind of distracting!

[bobke]

I'm with LRRPF52, scales out awfully close to .20 caliber....

[JASmith]

The bullet is the 55 gr Berger seated about one caliber deep.

In other words a 20 Titan?

Check out Todd Kindlers little book on twenty cals.

In other words a 20 Titan?

Close but not quite.

I found the Titan when I was doing research on this cartridge. Problem is that, after the first excitement, there haven't been many discussions on the web since. The Titan and this cartridge both have case volumes right between the 20 PPC and the 20 BR making its performance very close to both. One can speculate that folks could more easily get dies and starting brass for both the PPC and the BR and there's a lot of folks who can advise and counsel on getting the most out of those two cartridges.

This cartridge is different than the Titan, however: 1) The case is designed (on good advice) to be formed and made ready for use with minimum operations; 2) The chamber throat and twist rate (1-8") are optimized for the heaviest 20 caliber bullets. The cartridge should have a fair bit of flexibility in AR frames where it can chuck heavy bullets out of ARs at magazine length -- the .204 Ruger can't do this and do very well in bolt guns running at higher pressures.

One of the subtleties on this cartridge is that, while it is indeed formed from (Hornady) Grendel brass, the case is ready to load after just two operations (unless you are an accuracy freak!). The chamber is designed to allow using the neck wall thickness one gets in forming the brass -- no reaming or turning needed.
[INDENT]Operation 1 -- Run through a 6mm full-length die (will ultimately use a purpose-built forming die)

Operation 2 -- Run through the Hornady full-length size die

Ready to load![/INDENT]
Barrel should be here soon!

A good friend has a 20 PPC on a Sako 461. Firing the 39gn bullets it is deadly on rabbits out to around 400m. Literally tears them apart.

Every bit as quick as the standard 204, but more accurate and less delicate with loads (powder/bullet/seating depth, etc).

To get the best from a 20 cal you must be prepared to neck turn your cases. Sorry, these smalls really do get fussy about little things.

I went with a 20 VarTarg built on a Rem X R 100 action. Have a best of 350m on rabbit so far although the areas I hunt now limit the reach a bit. Love the effectivness of this little 20 and the Grendel holds the same facination with its ability to feach way out past where its is thought to be effective.

Hmmm, I wondered if Hornady simply copied or my tweaked my FL die specs from 07'

There is a possibility that several of us have been thinking along similar lines.

Are you referring to the .20 Grendel described at (http://www.65grendel.com/forum/showthrea...-Grendel)?

If so, Hornady built the dies to a drawing I created and sent to them and to Manson reamers. BTW, the neck diameter is set to allow simple sizing from 6.5 Grendel brass without any need for neck turning.

Referring to Bwaites' picture in the OP, I discovered that I can go from 6.5 to .204 in two steps by using a 6mm PPC as the intermediate die. The difference, I think, is that the bushing presents a very sharp radius that the brass has a hard time moving around, and the standard FL die does not have that feature.

Yes, I had some 55-57 grain VLD .20 bullets made back in 07' along with FL sizer die from Hornady. Along that time Bill A became interested when I posted pics of the VLD's and the cartridge necked down to .20 caliber, this was well before the 55 grain Berger BT existed.
