Exhausted the search for this exact load and found basically nothing. Reason I ask is I know the powder “works” but I’m just wondering if I can get some specific hands on experienced feedback from this combo. I have a lead on a good stash of this powder local, so I’m wondering if it’s worth my time to work with or is it a no starter from the get go. Just curious as I’m finding the usual go to powders very elusive locally.

I think it is a bit fast for the creed, I use it in my 224V. I have run N560 and N160 in a Creed with good results, but the best powder I have found for the Creed and 140 family of projectiles is RL16.
Edit to add: I have also run N555 with good results - N555 was developed for the Creedmoor type cases and they claim it to be temp stable.

I've had good luck with N550 and the 123gr ELD in my 6.5 Creedmoor. For 140gr bullets though, H4350 does better for me.
Can you tell me what barrel length and velocity you are getting with that combo with the 123gr ELD?
Sure, I'm using 40.5gr of N550. My velocity is about 2730fps, and I've got a 22" barrel.
Awesome, thank you for the info I appreciate it. I know The HMFIC of the site is big on speed over most other things so maybe with my more available local powders I should chase that speed with the slightly lighter bullets. Now Ive got some decisions to make I guess.
Are you familiar with the velocity potential of it with the 136-144gr bullets then? Preferably in a 24” barrel, but any barrel length velocity info in that bullet grain weight range would give me an idea.
I shoot 6.5x47L, which is obviously very similar to 6.5C, but not exactly the same. The Creedmoor has a bit more case capacity, so it's got potential for slightly higher velocities, but the 6.5x47L has a longer neck which allows for longer seating. So just keep that in mind. I shoot the 144s @2800fps in a 26" barrel.
QL load says that you're going to get similar velocities with 6.5C in a 24" barrel using N550

my old barrel 26'' bartlein loved n555 at 43.6gr pushing a 140 gr bullet 2802 max 2748 min 2776 avg with a sd of 13.2 not the greatest sd's but it shot great groups great being 5 shots under a dime at 100 yards my new barrel same as the other one but new likes
42.0gr 2746 max 2728 min 2740 avg with an sd of 7.8
42.8gr 2767 max 2751 min 2758 avg and an sd of 6.0
43.1gr 2794 max 2776 min 2786 avg and an sd of 8.6 , Id take any of the 3's number again any day of the week if I could get them again best of luck to you finding your favorite loads with n555 hope it works just as good or better for you .

Was the N560 temp sensitive or does it burn out barrels faster like I have heard N570 does?Rifle reloading data | Handloading | Rifle calibers | Centerfire Rifle bullets | Reload your own ammo - Vihtavuori

The N500-series powders generate more heat and therefore more velocity. The N100-series do not generate the same amount of heat, but have similar burn rates to their N500-series companions (ie N160 vs N560), which is why they're often preferred for semi-autos or any fast-string shooting over the N500-series but can't generate similar speeds.
