@Broc , I am no expert in reloading, but have you considered the stable velocity nodes? I am still learning and have found that SD and ES numbers become important only in stable velocity areas. If one were to look at the velocity vs. powder load graph, there are areas where the velocity does not grow at the same rate. Those areas are where I start chasing SD ES. For example, here's the graph of the initial ladder work up on 6.5 Grendel load development:
This particular ladder was done in 0.2gr increments and two shots per weight. As you will notice, there are many spots where ES is very low. For example, at 28.4gr, the spread is just nine fps, but because the velocity at that station is growing fairly consistently, the precision is not very good. If one were to look at 28.8-29.2gr stations, the velocity is barely increasing. Good candidates on this particular workup were 28.0 and 29.0. The follow-up workup was 0.1gr increments for 0.2gr in each direction to confirm stability and precision. The 28.0gr area ended up being discarded, and I focused on 29.0gr.
I was developing this for my Howa Mini 6.5 Grendel hunting/plinking rifle. The action is advertised as 1MOA and that is exactly what I get with factory ammo. My ammo gives me a very consistent .75 MOA which I'm happy with.
I am still learning and would love to see your feedback on my work up.
SD < 10 is great.
FWIW, I've seen the same thing with excellent SD but poor grouping and, conversely, great grouping at much higher SD. I assume that it just happens to be in a bad spot relative to the nodes == PITA.
Ahhh.... 6.5...... The .40 S&W of the rifle world...

Two of the most versatile calibers ever made! 308 is ancient and useless. 9mm is older than 45 ACP which is older than dirt.
better yet, combine .40 with a Creedmoor Magnum case and what do you get!? That's right: the 408 CheyTac!!!

Lmfao 6.5 is better at everything than 270win
They also have soft shoulders... They switched to the .308 from the 30-06 because they were pussies.
"we want a short action"... yea.... sure you do...
At distance, that good grouped high SD load will open up vertically. You just don’t see much vertical separation due to velocity variation within the first couple hundred yards. But it gets exaggerated at distance.
That is what bothers the .40 fan bois. It was literally a cartridge designed for weak people.
Where the 6.5 was designed to have awesome BC and is super easy to reload. No need to f*ck with 7 powders and 20 bullet weights.

Brah, agree!

Mark Boardman and Ryan Muckenhirn sit down to pit the prom queen 6.5 Creed against the more than iconic .308 Win. After chatting through the merits of both (which both have many), they decide more research needs to be done. Research that requires guns, ammunition, and ballistics gel. If you’re...
Oh, and the video version for those who need visual cues.

No one asked you!! (The link for me has some issue)Actually, you can compare them...Vortex Nation Podcast • Ep. 287 | .308 Versus 6.5 Creedmoor. Who Reigns Supreme? • Listen on Fountain

Dude, this is NES. Everyone has an opinion that is more correct than your opinion.
You probably need the fountain.fm app. It is a podcasting app that pays you in Satoshis to listen.

Yea, you're right... When it comes to things like chamber pressures, barrel life, down range energy.... the 6.5 doesn't hold a candle to the .30 cals. There simply is no comparison. I mean hell, if you really wanted to go full vaginal sniper, you could at least argue for the 6.5 PRC.... But Creedmore.... That's a cute little rifle you got there. Does your non-binary adolescent they/them kid enjoy shooting it?
The exact same thing could be said about the 6.5 Creedmore. It's for man bun wearing, straight-edge, gender studies majors afraid of the .270.

I got to run a Ruger American pair in . 308 and 6.5CM with the same PST2 Vortex scope. There was a Savage 110 in . 308 there too, but I only put 3 rounds through it.
I went 12/15 on a gong at 600 yards with the 6.5 American. 6/15 with the . 308.
He didn't have his 1000yrd range setup this year (had to move a road due to erosion and didn't put everything back yet ).
The same rifles, a few years ago, did about the same, with . 308 really struggling at 1k in light wind. The thing that really surprised me was the lack of recoil of the 6.5.
His favorite is still the Savage 110, but the barrel was getting a little off. It's what he shoots pretty much every day.
He was building up a 6cm or 6 dasher on a JP to replace the . 308.
EDIT: I can't believe I just read thru this whole thread. Wow. More entertainment than Saturday night live!
