Anyone using IMR 4064 in a 6.5x47?

Is anyone using IMR 4064 in a 6.5x47 Lapua? I’ve been using varget with a 123gr scenar with great results but I have a ton of 4064 laying around that I could use too. Hodgdon website shows nearly identical max loads and velocities between the two powders. Can they (varget and 4064) be reliably interchanged? Any other load dat for imr 4064 in a 6.5x47 also welcome, especially for 123gr bullets. Thanks guys!

Tag.. I am curious as well. I have a lot of that powder.

Got a little bit of info for you guys. I went out a few weeks ago and shot 37.0, 37.3, 37.6 gr of IMR 4064 in my 6.5x47 Lapua with 123gr Lapua scenars. My usual load is 37.4 gr of Varget with the same bullet. Results were that 4064 was reasonable bit slower. 37gr IMR 4064 averaged 7294 FPS, 37.3gr averaged 2806 fps, and 37.6gr averaged 2807 fps. With my normal load of 37.4 gr of Varget and a 123gr Scenar I get 2875 FPS.
Accuracy was good. I was shooting off of a rear squeeze bag and an atlas bipod. Groups were about the same as my Varget load, maybe slightly bigger. I wasn't taking the most careful shot since I was mostly interested in velocity data at this point. Im hoping to get back out and test some heavier loads here pretty soon.

I have wondered the same for both 6.5 & 6mm Creedmoor. IMR 4064 has been the most accurate powder in my .250 A.I. with 100 grain bullets, which is very much same type case capacity vs. bullet weight.
