It will be a flame thrower also. Link to comment Share on other sites More sharing options...
EDA Posted July 1, 2015 Share Posted July 1, 2015 I'd be curious as to what length barrel and the COAL as well. Link to comment Share on other sites More sharing options...

Aircooled6racer Posted July 2, 2015 Share Posted July 2, 2015 Hello: There are better 9mm powders out there than 3N37. It is a barrel burner powder. It heats the barrel up a lot. You could try Winchester Auto Comp, Ramshot Silhouette or Hodgdon HS-6. All work better for me than 3N37. Thanks, Eric Link to comment Share on other sites More sharing options...

Thanks, Eric Thank Eric, what I have available to me is 3n37 and 3n38. 3n38 is a huge pain because 9.2 grains in a 9mm case is quite full, but it does work. I guess I need to get my hands on some others to try. Link to comment Share on other sites More sharing options...
Cowboy1629 Posted July 2, 2015 Share Posted July 2, 2015 Last time I used 3N37 I was running 7.9gr at 1.165 with 124gr JHP and small rifle primers. Was getting 170pf with full size gun no barrel holes. It will heat your gun up but if you have no other choice it will work. Link to comment Share on other sites More sharing options...
seanc Posted July 4, 2015 Share Posted July 4, 2015 I loaded this today. CCI SPP primers, 1.18 COAL with 7.9 grains, 124g xtreme double plated bullets. 10 shots were 1403-1411 FPS from a 5" trubor. To my hand/eyes in this gun, I could not tell the difference between it and 9.2 of 3n38. Link to comment Share on other sites More sharing options...
