Yup, I've used it in my 6.5CM. When things were getting tight and powder shortages were forecast, I bought some to see if it was a suitable alternative. Simple answer, yes it was and is a suitable alternative. With the right load it shot the same poi and speed as my loads using 4350. It flows easily through the powder measure. And gave me an extra 200fps in a 270 I was playing with. Excellent powder, but it is a bit temperature sensitive, so I dont leave loaded cartridges lying around in the sun on a hot day. For me it is a viable alternative to my regular load and I can change from one to the other with no variation. And I've used it confidently out to 1400 metres.
