6.5 Cartridges

[diver160651]

The shorter action can be lighter and stiffer.

SA vrs LA.. It really is not as much about the stiffness, that can be overcome.

One of the biggest benefits (for many) to SA, is you can rack when still on the gun. Not everyone cares about it, but a large segment of shooters do.

When a cartridge comes out it immediately gets wildcatted by taking out body taper adjusting the shoulder angle and lengthening shortening the neck. The 6.5 is no different in that just about every combination has been tried.
The combinations that work or seemingly work gain in popularity and the rest fade away until new powders/primers/bullets come out then they all get tried again.

+1
Probably the best, concise summary I have read with reference to any caliber an average enthusiast could manufacture or have access to.

Looking at different manuals, whats the big deal/difference between the 6.5 Grendel, 6.5 Creedmoor, 6.5x55mm Swedish Mauser and the .260 Rem?
I honestly don't know anything about these rounds,but, gadzooks, other than the Swede, it's all I hear about. They don't seem that far apart. Curious.

The difference is length and powder capacity and therefore velocity with a given weight class of bullets.

The 6.5 Grenade is specifically made to fit in an AR-15 with it's 2.25"ish magazine length restriction.
The 6.5 Creedmoor was made to be able to shoot 140gr target bullets in a 2.8" magazine length short-action bolt rifles.
The 260 was originally conceived as a hunting cartridge and is simple the 308 necked down to 6.5mm that also fits in a 2.8" length short action bolt rifle, but you have to deep-seat the 140gr target bullets to get them to 2.8" OAL.
The 6.5x55 is a long action cartridge and will beat the velocity of all the smaller 6.5's.

I smacked my face once running a long action like I do a short action.
Never again.
Now I lift my head off the stock like most hunters do after they fire a shot...

LynnJr and Randall, thank you for specific answers. I don't plan on getting one of these, but, I've heard so much about the 6.5 this and 6.5 that, I was curious.
Thanks again. Thinking of recreational target shooting, maybe one of these may work. Or a .243, or .223. Hmm.

.243 great cartridge, but can eat barrels in a target environment.. lot od .243/6mm variants that are a bit softer. From the Dasher, then the Creed to the 6br.. One is very fast, one has factory ammo and one is good on barrels... all shoot well. Maybe Lynn or Randell will jump in.

But the deal is it really does not mater what you shot, but how much quality practice you do

In some types of shooting (as you know) we spend so much time learning to keep on the gun and rack quickly while self-spotting, that staying down and on the scope, becomes ingrained.

I purposely set my scopes a bit back on my hunting rifles, so when prone (face a hair more forward) I don't get waked as hard.. maybe just a kiss..but I have yet to remember to lift my head..

On a side unrelated note, getting smacked in the nose with a bolt isn't nearly as painful as putting a 270 in a 300wm or in a 7mag (damn I am dumb I have done both)--- I have a peppered pic of my ugly face somewhere..

And no mention of 6.5/257 ? oldie but a goodie

I ran the bolt on my 50bmg into my teeth once.

There's more to it than that Randall. The 6mm PPC taught us the importance of the powder column, a soft primer and the internal shoulder angle. Newer cartridges are trying to take advantage of this knowledge, at least some of them are...lol.

You might as well. Because the 6.5 Creedmoor was brought into the mainstream, there's not really a penalty you have to pay to shoot it. High quality ammo is widely available, you don't have to be a handloading alchemist. It's also not real hard on barrels.

If you're also considering a .223 type of chambering, by the end of the year you'll probably be able to find a .224 Valkyrie in a lot of rifles. It has the same design philosophy as the Creedmoor - a short case relative to the overall length so long (low drag) bullets can be used. In youtubes so far, it's been shown to pretty much be the ballistic equivalent of the 6.5 Creedmoor. Smaller, cheaper bullets, less powder, etc so that over time, ammo costs should be less.

[pennstater]

If I get into any type of recreational target shooting, it would be a conventional round; .243, .223, something like that. No hardcore shooting, just some rounds down range. Nothing serious on my part. You know, retired guy stuff.

6.5 Grendel is not in the same class as the 6.5 Creedmoor, .260
Remington and 6.5x55. As previously stated it was designed to be used in an AR-15 upper and as such has considerably less powder capacity. My 6.5 is a Swede in a modern action and I see no need for a Creedmoor. I’m jonesing for a 6.5 SAUM though.

I just want to know the load data for this new cartridge!!!

About 35 grains of Retumbo behind a 123 grain bullet seated 5 or 6 thousands into the lands should do it.
