308 Superior to 6.5 Creedmoor CONFIRMED

[rlsmith1]

Just got done measuring velocity from my 2 AR10 uppers and numbers don’t lie.

6.5 Creed 140 FMJ at 2480 is supersonic to 920 yards (0.4 MOA group)

308 Win 175 SMK at 2490 is supersonic to 1080 (1.25 MOA group)

To boot, the Creed has a 18” Criterion barrel vs the 308’s Ballistic Advantage 16” barrel.

Factory ammo out of both rifles.

Don’t talk to me about anecdotal evidence, efficient 6.5 bullets, drop or wind drift. Almost posted this in bear pit

2480 is stupid slow for a 6.5 CM.

 

[JMGlasgow]

More than double the group size from the 308 and it's superior?

And 6.5 Creedmoor short barrels are stupid. Might as well just shoot a Grendel.

 

[sirhrmechanic]

And in other news, BMW owners don’t know what turn signals are and Serbu’s blow up.

Just ‘sayin.

My 6.5 Grendel shooting a 123 gr ELD-M at 2450 fps is super sonic past what your 308 is, from an 18" AR15. That make the Grendel superior to the 308- with data to back it up- right?

I would also kindly ask you not to reference velocity

First, yes; velocity is paramount. Second, everyone knows small frame ARs with the right cartridge actually outperform large frame ARs in similar calibers. My apologies for leaving this out of my first post.

Mods, I realized this might have been better suited for advanced marksmanship!!

Please see my apology above.

Secondly, I’m only looking at efficient 308 bullets here ok? This must be what liberals feel like when they selectively use data!

Compare a tier 1 308 round to a tier 1 6.5

personally I like my 308/7.62 for many reasons and if I went to a different chamber it would be something a little hotter than 6.5

I don’t want to!!!

The only criteria where 308win beats- anything- is in factory ammunition availability.

I agree but I’d add the points above as to why 308 is CONFIRMED superior

Before all the covid hysteria, the used to shoot M80 ball like it was nothing, and inside of 500yrds it worked 90% as well as nice 308 rounds and at a fraction of the price.

Throwing away 2 rounds per box eats away at much of the cost savings...

Yeah I agree with hlee, M80 is so inaccurate even the great marksman @TheHorta couldn't get it to group

the internet doesnt lie, must be true.

I didn’t have all that many flyers

Magtech boxes of 50

Maybe with old ass surplus crap maybe?

It's all about bullet weight.
Physics.
I can lob big heavy bullets at low velocity and they will retain energy much better than light fast bullets due only to bullet weight.
You guys do know that buffalo hunters were shooting old Sharps rifles 800-1000 yards and more in the 1800s, stuff like 45-110 to 50-140.
Those old heavy bullets retained enough energy to kill a buffalo at that same 1000 yards.
Try that with your manbun cartridge of the weak.....I mean week.

Id still go with god and his favorate round 6.5 creedmoor if it good enough to make god smile it's good enough to make me smile oh thank you oh lord for your bless id rounds and 6.5 is thi name . lol

Why not just 6BRA it if we’re going away from plentiful NATO chambers?

I'm just working on your numbers. If M80 worked 90% as well as match ammo, then you were looking at 5 per 50 that weren't going where you thought they should...

But for the price point and just plinking steel

And the ones that didn’t group that well, still impacted, wasn’t like “where the fuck did that go?”

 

[KZP]

.308 is superior because the larger bullet diameter increases your chance of hitting the target. Going to 6.5 gives up that extra 1.12mm of possibility. You gotta be a real dummy to to throw away that extra potential.

Use-case is everything.

True, just saying, it’s nice for practice to be able to use 762x51, the next rifle I need to get off my ass to build is going to be 6BRA, just don’t see the ROI with 6.5,

More or less for precision I just see the progression like this

22LR
223 wylde
308
6bra
338

Probably had an mrad scope on the 6.5, that hindered the performance drastically

The larger black spot is easier to see.

It matters not how "superior" 6.5C is if you can't buy ammo for it.

"My 6.5C is better than .308 and I will prove it just as soon as I can find some ammo for it" isn't much of an argument. LOL

Couldn’t have said it better myself

Breaking news, Same scope, a VORTEX in MRAD!

Can confirm my chili has beans and Texas will be blue in 2024 because of their stance on this issue alone

 

[GUNNER10]

Well...

This revelation certainly closes this debate.

there’s plenty of factory ammo around.... that hardly anyone buys more than a little of because it’s pure hunting ammo.

reloading is the light and the way...... unless you’re like me and still can’t match the best factory stuff with a handload. It creates a crippling addiction to federal terminal ascent ammo for anything serious

 

[Tchitcherine]

The Science Is Settled™.

 

[357Max]

Stop shooting Aguila in the Creedmoor, don't take that fat girl home when the bar closes, & let us know if you feel the same about the 308 in the morning.

Found some in my reloading room the other day ???

No kidding, the fact the Criterion shot it well is more a testament to the barrel than anything.

It’s morning, and I still like shooting my 308 at half the price of the Creed . If I’m spending $2 / shot I’ll just grab the 6mm at this point. I hope that changes soon but doubt it.

I do enjoy my hand loads that are 140 HPBTs closer to 2600 (SD of 9.2) out of this barrel

[DocRDS]

Ask yourself why there are no ARs in 30-06.

Because the sheer amount of awesome available would be too much for the human race to handle.

Why does a Garand go "ping"? Because God wanted to announce to the world: "8 more rounds of God Given Awesome bout to go in!"
