With all that said maybe you can answer my thoughts. Ive been pondering my next rifle. I want a bolt gun from precision firearms that will shoot out to 1k at sea level through my 6.5 ultra 7 suppressor and be enjoyable to shoot. My savage bolt 270 (before my suppressor) was not fun to shoot which is why i sold it. Can't decide on caliber and i do reload. Im new to reloading but very thorough.

[LRRPF52]

Bolt gun out to 1k through Ultra 7 6.5?

6.5 Creedmoor

Where I was going with the thread is looking at the success vs "never heard of it" in relation to these recent cartridges.

What makes one gain traction, vs one that has all the backing from the biggest rifle/ammo manufacturers with huge marketing budgets and glossy ads in all the major gun rags, and is a total flop?

[FRB6.5]

Pretty sure .300 Whisper was created in the early 1990's (J.D. Jones/SSK). I recall shooting a memorial match in Tucson 1995, for the late Bruce Nelson. There was a competitor running a suppressed .300 Whisper AR.

There is also a .375 Cheytac that is popular for ELR.

[FRB6.5]

.22 Nosler and .224 Valkyrie also fit your timeline and theme.

Despite just about every AR manufacturer making .224 Valkyrie uppers and barrels it seems to be a flop. Ammo isn't common on any store shelf and performance is well short of the hype (unless you have a very long barrel).
LaRue wasn't even shipping their SUURG in .224 V and seem to have removed it even as an selection due to performance issues.

Roger that. The list I'm working off of has dates of formal acceptance. Some of them seem off to me.

I remember when .300 Whisper was first mentioned and it was a JD Jones creation in the 1990s. I mentioned that in the other thread about advertising or lack thereof for 6.5 Grendel.

Of all these cartridges, I bet 6.5 Grendel, .300 BLK, and .17 HMR have the highest production numbers, along with 6.5 Creedmoor and 6.8 SPC.

[Growler]

6.5 PRC belongs in this list.

Agree with your main point, lots of one hit wonders, with a few that are here to stay.

Bigs another 1K nice shooter is the 6mm Creed. Plus you can go small with varmint rounds and grandkid-type loads. With a 90 gr Sierra TGK almost like an air gun.
They have gtg rifles or you could get a Savage or Ruger Predator and spruce it up.
For bolt actions...

The case slightly smaller than a 243 means you get to use more medium-burn powders like Varget and H4350... and load out to a 115 gr target load, nice BCs.

[Arkhangel5]

The 450 Bushmaster needs to be in bold.

And seems to be popular these days, in states with straight wall cartridge hunting restrictions.

And I own one, just because.

Bigs,
Damn man!!!! Shoot the fag-mag....6.5X284.

I have a BAT Model M that Speedy Gonzales smithed for me with 2 fresh pipes..

I will be glad to send it to you if you want to shoot it for a while.

Live Big ,

LaRue wasn't even shipping their SUURG in .224 V and seem to have removed it even as an selection due to performance issues.

Federal screwed up the launch of Valkyrie with bullets, reloading info, barrel twist, etc. Early barrel reamers were pretty much junk as well.

Now that it?s been out and people have played with it, it can be a very accurate cartridge. A proper 1:7 twist or a newer 1:6.5 can shoot 80gr to 90gr+ bullets very accurately. H4895 is, by far, the best powder as well.

Not the answer to everything but 80-88grs pushing 2800fps isn?t bad at all. It is 100% a hand-loaders cartridge right now

How did we ever kill an animal with only a 30-30 or a 30-06.

Imagine what the cartridge list looks like from say 1960.

How many of these will fade into obscurity.....

I bet you that every member of this forum is just a little bit different from the normal rank and file or else we wouldn?t be shooting the Grendel....

[kmon]

CJW, I would fit that description with cartridge choice, never owned a 30-06 or 270.

In 6.5s my first one was a 264 Win Mag, followed by a 6.5X54MS then a Grendel followed by a 6.5-284 and another Grendel. I do own a 30-30 but it not quit the usual lever, a Remington 788. I have hunted and killed deer with bullets of .172, .224, .244, .257, .264, .277, .284, .308, .338, .357, .358, .375, .378, .429 and .458 and multiple cartridges chambered for several of those. In reality none of them killed any better than the little Grendel, some made more of a mess than others but all worked, just at this stage in life I am liking the efficiency and gentleness of the Grendel monster.

[LRRPF52]

I grew up listening to my Grandpa talk about the merits of the .257 Roberts.

Sure, he owned a .30-06 as well, but he loved that little Japanese Arisaka that he re-barreled and chambered in .257 Bob, with a sporterized stock that was common for gunsmiths to do in the post-World War II era in the US.

It would be interesting to see the statistics on production numbers for each of the new cartridges that have been introduced over the years.

I can tell you that 6.5 Grendel has a lot better numbers than most of the ones on that list, and is in the top 3 of all those center-fired cartridges, maybe even 1st. Since .300 AAC just barely started having steel case made for it, there's a good chance 6.5 Grendel ammo production from all the major manufacturers has eclipsed .300 Blackout, which has been marketed heavily by Remington/Freedom Group while having some of the worst ballistics of all the new centerfire rifle cartridges available for the AR15, if not the worst when looking at supersonic loads. This shouldn't surprise anyone since the cartridge dimensions were primarily intended for subsonic use, with a supersonic option shooting lighter bullets.

If I was going to pick 3 of those 2000-2020 cartridges that will continue to drive on in popularity, they would be:

6.5 Grendel
6.5 Creedmoor
.300 Blackout

Since the 6.5 Creedmoor is not able to fit in the AR15 frame, I think it's a testament to how well Hornady has marketed and supported the Creedmoor, along with its obvious real-world performance that sells itself in-place of where most people used to get .243 Winchester and .308 Winchester.
