This is false. I don't know if you're intentionally lying or just ignorant.

Not really true.

Load Data from Berger's new 156gr is 2650fps at the muzzle.

The creedmoor is capable of much higher pressures than the Swede (62k CM vs 51k swede). As such, the Creedmoor is pushing a little faster.

A 6.5 x 55 and a 6.5 creedmore are exactly the same caliber. Meaning the bullets are of the same diameter. Meaning, if you handload, any bullet you load into a cartridge will work in either cartridge.

I think you are confused.


Also the same is true of a 260 Remington 6.5 Remington mag and 265 Winchester mag.


Every cartridge I listed uses a .264 bullet.

Have y’all taken a look at a 6.5 PRC? 28% more powder than a 6.5 CM.

Yes. Quite a bit.

I think Got Blaze has one. Pretty interesting round.

not sure if it's worth it for what I'd be doing though.

Where does all that stuff stack up with the 264 win mag?

The 264 win mag was the original commercial souped up 6.5 and it basically flopped. 6.5-284 has also been around a long arse time. Neither of those has ever been immensely popular. Why are 6.5's all of a sudden so popular that any new 6.5 garners interest?

PRS matches and long range shooting competitions have popped up to be a lot more common now than they were 10yrs ago. Optics have helped with that tremendously as well, in my opinion.

I don’t know too much about the .264 wm other than it never caught on and went away pretty quickly. I’d guess the 7mm mag took some of its shine when It was introduced.

I looked it up: the 6.5-284 was introduced in 1999. The .260 was introduced in 1997.
Just FYI

A lot has to do with the competitions, but id give more credit to being at war for such a long arse time. A lot of guys that started the PRS/tactical match craze were or still are former military. Hell, special forces groups will send snipers to compete in matches as training. Its pretty cool.

Its really a combo of a bunch of things, but 6.5 calibers offer a longer barrel life than 6mm calibers and increased lethality/hit probabilities/lighter recoil over 308 rifles. Add in the short action for a little weight savings and boom you have a new revolutionary caliber. The market caught up with competitions though and they have shifted to 6mm calibers since custom actions have such tight tolerances now gunsmiths can simply chamber barrels based on one action and they will headspace perfectly on all those actions. No more downtime sending a rifle to a Smith. Just order 2 or 3 barrels for a season and go.


Just my opinion. But it seems we just went through a perfect storm of weapons development.

And 6.5 bullet options have exploded in the past 10 years.

I don't think anyone has an issue with the caliber, more so the marketing hype that has made Bubba think he's an expert on 1000 yard ballistic sectional coefficients and needs to tell me all the frick about it.


6.5 CM is the CrossFit of the cartridge world. Anyone that shoots one won’t shut up about it.

I didnt know we had hit this point finally. I never realized how sloppy factory tolerances on rifles were until I started researching building one. Blew my mind that I couldn't just screw a new barrel onto an old 700.

So 3 years from now will it be the 300 prc?

Actually, hit this point with surgeon rifles a long time ago, but nobody knew it. Before they sold to strategic armory they had the most consistent action available. Wade and them sold it and started Impact precision. I think the internet and gunsmiths are just catching on much more quickly now. There are probably 10+ actions that have prefit shouldered barrels available now. Of course they will warn you to check headspace, but whats better a $50+ set a guages or 6 months at a gunsmith?

The .264 WIN Mag and 6.5 x .284 are both outstanding rounds. A lot of it just has to do with timing and marketing.

Increased lethality over 308? What do you mean by that?

More or less lethality of the weapon system. If you can hit the target XX% more with a smaller cartridge then it makes the system more lethal.

Not talking about stopping power.

Check out the mathematical approach:

Obviously, this isnt real life with shooters and differing conditions, but its a good place to start.

I think it passes up the .308 somewhere way the shite out there. Way farther than most people have any business shooting at game. I think that in the heavier rifles it probably allows you to see your own hits as well where the .308 with heavy bullets has a fair bit more recoil.

I shot a deer this year at 230 steps from prone. That's close enough that ballistics are largely irrelevant with any deer caliber but far enough that it wasnt an easy shot. People concerning themselves with shooting deer at 500 yards and further are largely hillarious. Many of them might shoot a dozen shots a year max but think their christianson creedmore makes them an 800 yard hunter. I get then opportunity to aim at deer at 700+ yards a whole lot, it's tough to keep the crosshairs on brown at that range, much less make a lethal hit. I'd never try it.

There are people out there (like kengal) that shoot alot and have the skills and equipment to shoot far enough where small differences matter alot. The majority of these guys should be worried about hitting deer at 150 yards from field positions, where the equipment is for the most part irrelevant. Any modern deer rifle with a decent scope will work.

He talks way too slow.
