That's awesome, I'm wanting to try them for hunting. Do you have any reloading information using any other powders?

[@frankiecrouch3918]

What are you going to run them out of and how long is the barrel?

@@AA-fg3wj my favorite bolt action powder for 300BLK subsonic is Win244. I think I am using 5.7grs for these and 5.9grs for the Hornady SubX. I have also found that this powder preferred CCI standard small rifle primers.

@@frankiecrouch3918 thanks, I will look for some. I have lil gun, aa1680 and h110

@@AA-fg3wj I think I did well with 9.5grs with h110 and 8.4 with lilgun, I'm not a fan of 1680 as I think that it's super loud load subsonic.
