16"bbl

[jp1949]

In Alabama you cannot go under a 16" bbl. With a 240 SMK what powder and charge weight do you think would be a good place to start?

9.2gr vihta vouri N110 is a good one. about the same charge weight of H110 will work but its much more temperature sensitive.

I run 11.3gr of 1680 in mine to stay subsonic.
