The Best New Cartridge No One's Talking About

[@atomicpsych0]

For all of you like me who hate suspense, the round is 6UM. I'll admit I've never heard of it but didn't want to wait to hear it. Others should copy this post so it doesn't get derrick at the bottom and others can see quickly. Very interesting ability this cartridge has, but I'll stick to a way less expensive round that doesn't destroy my barrel that fast. Super cool stuff but over $3 around and barrel done in 800 rounds is crazy brother

[@JustAnotherGuyAdventures]

Haha that’s the whole point

[@kingy300wby]

I can appreciate a fast 6mm my mate built a 6-284 Norma and is running 87gr vmax at 3600fps, he uses it for head shots on meat animals, very flat shooting and hard hitting. I like different types of cartridges they are cool, thanks for sharing 👍🏼

[@JustAnotherGuyAdventures]

Thank you!

[@garageliving3658]

Under rated/less talked about is the 6.8 western and 22 arc

[@JustAnotherGuyAdventures]

I don’t disagree that 22 arc has caught my eye not for the same reasons as the 6 UM but diffidently like it!

[@ChrisB-uj6zi]

6mm rem has been around since the 1940’s and velocities range from 3100 to 3400. These “ New” calibers are a joke.

[@JustAnotherGuyAdventures]

Not shooting a 115gr bullet it’s not doing 3400fps?

[@ChrisB-uj6zi]

With Hand loads 3200, so I don’t see the big difference. 200fps with the same bullet and readily available ammo it’s a no brainer.

He doesn't mean the same. He means similar. Alot of people can't comprehend the difference between 22creed and 22-250 or 300wim vs 300prc . Sometimes people want as fast as velocities as possible so they can run a shorter barrel with a suppressor. The 270 win does not do what the 6.8 western does! U have diff rifling twist rates vs longer chambers

I think it's funny how people are always worried about barrel life. I see it as if you can afford the ammo to burn the barrel out you could afford a new barrel

[@JustAnotherGuyAdventures]

Right

[@clunesadventures]

Great video and explanation of the cartridge. I've been intrigued about it since listening to the Shoot2Hunt podcast. Seems like it fits so many of the North American species in reasonable hunting distances (and maybe beyond for those skilled enough) with recoil that's very manageable for all hunters.

[@JustAnotherGuyAdventures]

I couldn’t agree more! It’s an awesome cartridge!

[@Howlin23]

What does an 80gr pill do out of one with a 22”-24” pipe?

[@JustAnotherGuyAdventures]

I can only imagine 4000ish

[@ArchersAnonymous-nb4ym]

Pretty impressive speeds in the 6mm family. Definitely a barrel scorcher if you shoot a decent amount but 3400fps in a 20" barrel< what do you expect lol? Wonder what it would do in a 24" or 26" barrel if your dropping 150fps in the 18" vs 20"?

[@JustAnotherGuyAdventures]

I’d guess close to 3600fps in a 24in screamer may 3700fps in a 26. 3250 is just where it landed on decent es and sd.

[@jeffreyherman2729]

The only issue I noticed about this video is calling it a long range big game cartridge. In the chart at 5:25 it shows the kentic energy at 1000 yards and it is only 880 ft/lbs. Most hunting style bullets only expand down to 1800 ft/lbs which would limit this gun to 400 yards. Can it be done or has it been done... sure. Should the typical Joe go out and think they can kill elk at 1,000 with any cartridge, absolutely not. Just know you rifle and bullet. Other then that, great infomative video about a round I have not heard about.

[@JustAnotherGuyAdventures]

That’s not actually true. Most bullet manufactures say bullets will expand down to 1800fps. Using velocity not energy I’ve heard the hornady guys even claim down to 1600 fps. I agree not everyone should be shooting out to 1000 and everyone should know their limit.

[@beavisbrowne3497]

Great cartridge! Reading all the comments lot of wimpy cartridge fans. They scared of anything that burns over 50 grains of powder.

[@ranchodeluxe1]

[@JustAnotherGuyAdventures]

Fair enough. I appreciate your feed back

[@jakeblack4095]

How does this compare to a 6/284??

[@JustAnotherGuyAdventures]

More case capacity by about 6grs roughly. So little bit faster. I don’t think you could get that 6-284 in a short action unless your shooting light for cal bullets!

[@eddieb4227]

I would like to see how the wssm or wsm cases stack up. Since the saum and wssm have the same head stamp diameter. If the saum is a better case then just a reamer would be needed. Not sure if saum case is longer than the wsm

[@JustAnotherGuyAdventures]

I believe the wsm is a bigger case than the saum

[@funigui]

Yea its a barrel burner, I know you think that 800 is a good life.. but I shoot thousands of shots a year. Its cool, but if you like shooting you better be prepared to replace barrels. The 6mm Creed is the same problem, and why the 6GT got so popular.

[@JustAnotherGuyAdventures]

I think field and stream did a survey a few years ago and they came up with the average person shoots 16 rounds a year. For the average guy there’s no such thing as a barrel burner. Like I said also have a different rifle you practice with all the time. Appreciate the feedback though!

It is a barrel burner lol good term.for the meaning of

[@JustAnotherGuyAdventures]

I strongly disagree. It’s been used to loosely in history with cartridges such as the 264 win. Which pretty much destroyed such a great cartridge for the era. With cartridges such as the 28 nosler which had moderate barrel life. It’s a horrible term.

[@JustAnotherGuyAdventures]

Impact Shooting just did a great video on 6.5 Creedmoor barrel life and cost to burn a barrel out. A lot less people are burning barrels out than everyone leads on so the term barrel burner is very over rated!
