Thank you for posting your data. I have a question or two.
I see the test was fired in February. I assume it was fired outdoors. What was the temperature when the test was fired?
Do you happen to know the cylinder gap measurement on your revolver?
In past tests I have found CFE Pistol to be a bit temperature sensitive. Not terrible by any means, but just enough to make me wonder about temperatures when test are run.
Also, it seems the expected velocities posted on the Hodgdon data site may be a little bit optimistic for CFE Pistol. As usual, different guns give different results.
The fact remains that lots of people are getting good, consistent accuracy with CFE Pistol powder. I really like the results I get with it.

temp as i recall was in the 50-55 range, western Oregon i mild in winter, though not near as wet as it should be lately... the 625 cylinder gap is 0.004 i to find it to be useful in several pistols and very good in the PCC...

That temp is a lot different than what I normally get here. In February, I usually have temps in the teens or lower. Big difference.

Thanks for the data, guys. I am going to buy a pound at the next gunshow to try it out. I'm still playing with the IMR Target and highly recommend it but this powder seems pretty good
