WTK: 180 poly coated cast in 10mm

[Dane R. Marley]

I have a new CMMG Banshee in 10mm. My LGS makes 180 gr poly coated .40 cal bullets. I need to push these bullets through my Banshee aroud 1200 ftps.

What powders would you suggest I use?

In testing 10 powders, BE-86 did the very best for me. Close by were N340 and N350.

Blue dot and AA #9 have worked well for me in 10mm.

N340 is my go to for 10mm. I get higher velocities at lower charge weights than others including Blue dot and Longshot both in real life and using Quickload for "what if" scenarios. Very clean too.
