Anyone using Superformance in 6.5 CM? VV N555?

So I got a pound of this awhile back to test in my Creedmoor, don't remember the details off the top of my head, but do remember I wasn't wowed by the results. Only ran the one test batch, so I still have a fair amount left, and have since rebuilt my Creedmoor, it's now wearing a longer barrel, and this is the slowest powder I have on hand, seems like they should be a good match. Looking to load the heavier bullets, have some Barne's 145's and Hornady 147's to try. Also have some VV N555 on hand, results with that have been very good for ES and SD, but again, that was in my old barrel. Anyway, if anyone has tried both, I'd love to hear how you think they compare, as well as general thoughts on either. Thanks!

I loaded some bullets with 555 recently, but have not been out to test them. So in for more info.

I never have used that powder. I've got some (superformance), but it seems it's got a narrow window for efficient use.

My go to for 6.5 CM has successfully been with H4350.

I'm interested though to hear what others have to say.
