I think @Rob01 might be running his 6.5 CMs at this length
Yup have been since 2008.
Factory 140 ELDs will be in the 2750-2850fps and the 147s were about 2740-2775fps depending on lot numbers for both obviously. You can easily load them to those speeds also.
28" is an excellent length for the Creedmoor. I am loading the 153 ATips in it now at 2680fps for matches. Below is my 28" M24 contour 8 twist Bartlein on my Origin action.

Man! This thing looks sick. How do you like that glass and do you find it compares to anything else, glass wise?
That's almost exactly the same as my build. Dumb question, are you loading the 153's light? 2680 seems kinda slow compared to the 147. Not criticism, just curious.Yup have been since 2008.

This is my CM rig with a 28” 1.25” straight contour 1:8” barrel. With 44.0gr of IMR4350 and the Berger 140gr Hybrid Target bullet, my velocity is 2880fps average.Anyone else running a 28" tube for 6.5 Cr? My gunsmith had one handy and made me a great deal on a Bartlien. It is a 1-8 twist M24 contour. What kind of velocities are you getting with 140 and 147 grain pills?
28" isn't that bad or uncommon. and still shorter than a 26" with a canThis is my CM rig with a 28” 1.25” straight contour 1:8” barrel. With 44.0gr of IMR4350 and the Berger 140gr Hybrid Target bullet, my velocity is 2880fps average.
If you’re going to do PRS, wouldn’t that 28” pipe be a tad long to maneuver easily?
I didn’t say it was bad. But it seemed long for maneuvering in prs. I’ve seem mostly 24’s and a few 26’s up here.28" isn't that bad or uncommon. and still shorter than a 26" with a can

It’s not long at all. No problems moving around props and stages with it. Got guys with 240 barrels and 6-8” cans that move around fine. It’s all about knowing and practicing with it.
I did about 3 barrels at 28", but I ran the 130 hybrids about 2920 or so. Now a 25 cm 28".
The length is fine.

They were fantastic. I shot them well to 1400 yards.How were those 130s working for you?

Another possibly dumb question. 147 ELDM vs. 140 ELDM?
I never had any trouble with the 147 gr ELDM, and prefer it over the 140 ELDM because of the higher BC. And also like the 150 gr SMK, probably the best..Both work but the 147s have a history of blowing up in some cases. I don't think that's an issue today but some may still prefer to steer away from them. If they work for you, run them.

I have ran the 147ELDM over 3000 fps in 24" with hybrid cases, with no bullet problems...maybe manufacturing changes to the bullet have been made...but use what you have confidence in, and what your barrel likes.
I'm stabilizing the 150 SMK in a 24" 8 twist, my new Bartlein 26" is 7.5 twist.Yup, thats why I said if they work for him, to use them.
When you used the 150 smk, were you twisted fast enough for it? Does a standard 8 twist work? And how long were you loading them?
I went and shot it today. I'm running the 140 ELDM over 41 gr of H4350. 5 shot velocity average was 2797. ES of 21 SD showed as 9.8. 100 yard 5 shot group was .42 moa. I kinda thought my velocity would be slightly higher as my 24" savage shoots the same load at 2772. That said, at .42 moa from the 1st 10 rounds, I'm pretty happy.
