6mm ARC

[rabiddawg]

Lol, what the hell is the benefit for me to try and convince you to try something new? If you don't like it, don't like it, no one else cares.

Terrible way to ask for data. If you want data, read first, ask questions to fill in the gaps later. Tramping into a thread and telling everyone you're not interested, but they should try and sell you on the idea anyway ain't a great way to pursue your education.

BTF said it best; the 6.5 Grendel is a hunting round that target shoots, the 6 ARC is a target round that hunts. Bill A. developed the Grendel first and foremost as an AR round for hunting whitetails. The fact that it has long range potential is almost a side benefit.

The 6 ARC was developed specifically as a designated marksman round in the AR. The fact that it stays supersonic at 1,000 in standard pressure is super cool. I have my doubts that the cartridge will ever be as versatile as the Grendel. Bullet selection in 6.5mm is too deep. Others have concerns about the capability of .243 projectiles:

"However, the .243 Winchester has limitations when used to hunt deer and other Class 2 game. The main limitation being the .243 bore size restricts the maximum weight of hunting bullets to about 105 grains. The .243 Winchester cartridge somewhat compensates for the bullet weight limitation by driving its bullets at high velocity."

I might wind up with a 6 ARC at some point, probably in a bolt gun. I'm in no rush though.

How does the SAAMI chamber compare to the 6.5 Grendel chambers? Compound taper? Grendel 2? Like LBC? Something else?

Just stirring the pot

That's the elephant in the room. Because nobody is talking about it that I can find.

Been on the 6mm ARC Facebook page the last few days researching real world velocity data for 24 and 12 inch barrel lengths as well.

For me and my useage, the juice ain't worth the squeese. Now if I didn't have a cz grendel and 2 short barreled grendels already. Then yea I would still be in the hunt for the 6mm ARC.

The velocity's I was able to find for a 11.5 inch shooting the match 6mm ARC ammo from hornady, was the same as my 120 gold dot handloads from my 12 and 12.5 inch grendels.

The velocity's I was able to find for 24 inch rifles compared to my 123 eld-m and 129 ablr handloads, wasn't enough for me to justify getting a long barreled 6mm arc.

True it was supersonic to 1000 yards but so are my 123 eld-m and 129 ablr handloads. I don't compete and shooting at a grand is just for fun for me, so no need for me to speed more money to get something new that does what I already have.

I still like it and will still keep up with it and still love to see more advancement of the grendel case concept and it does have advantages in drop and drift. Just not enough for my usage to warrant the expense to get into a new round.

Very first post in this 11 page thread has the SAAMI link, all that was available when that post was made.

Think I will drop this here

I knew at that time it was Hornady, but promised who told me I would not tell.

Good job on opsec! I didn't hear a peep about any of it until SAAMI specs went public.

Ian thinks 6.5 Grendel is pointless, so probably not...

Here is some specific data.

Ian thinks 6.5 Grendel is pointless, so probably not...

It seems that Ian and Karl are satisfied with 5.56x45 performance. The Grendel was partly designed to replace that round*, so it's not surprising that they haven't shown much interest.

*Arne Brennan, a co-developer of the Grendel, on the other hand, largely wanted to shoot an AR in long range competitions with Lapua's then-new 6.5mm Scenars.

To add fuel to the fire...I went with the 6.5 Grendel for the 120-130 grains with good ballistics. I chose this over the lighter grain 22 Nosler and 224 Valkyrie. So what are the Horde members reasons to go 6MM ARC vs 6.5 Grendel?
