Good Afternoon all,
I have somewhat of a two part question for you.
First off, I do not own/ have access to a chrono at this time.
I am looking for some guidance on a suppressed load for my CMMG Banshee Mk10.
8" barrel, SilencerCo Octane 45.
Current loading is:
180 gr SNS coated TCFP
12.3 gr AA#9 ( out of Western Powder guide )
CCI 300 lg primer
Starline and FC brass
1.260" coal
I can still hear the sonic "crack" when these are fired, so obviously they are not Subsonic at that charge weight --- the 12.3 gr charge is a guesstimate from the load data to be 1075 fps --- I see that is incorrect now...
Also, firing these loads from the Banshee, it is INCREDABLY dirty, but firing them from my GP100 and a RIA 1911 they burn relatively clean. I realize the suppressor will cause some of that, but it seems excessive to me.
I have tried charges of 11.0 - 12.0 gr of AA#9 -- still dirty
13.8 gr of AA#9 -- seems excessively hot, although primers were JUST starting to show slight flattening.
I may be chasing the impossible ,but, is there a middle ground that would be subsonic and relatively cleaner than my current attempts...?
So is there any guidance from those with experience with this particular firearm, and insight from you more "seasoned" handloaders...?
Thanks in advance...
