The best that I have been able to do is 1090 fps with 124 gold dots in my P365.

In fairness, 1.25" of the 3" barrel is the chamber. So, being able to get 1090 from that little pocket pistol, is about as good as I could expect to get.

It's a bit snappy.

And if anyone cares, I used BE-86 powder to get there.

And for those that are concerned about flash, be-86 does have a flash suppressant. Though, that doesn't gaurantee there won't be any flash at all.
