lablover Posted October 3, 2012 Share Posted October 3, 2012 A buddy gave me a pound of this and said to try it with the 9mm. I checked the VV manual and loaded 4.5 gr of 3N37 and a 147 cmj MG. SHot real nice and soft and was pretty accurate. My question is I say most people using N320 for the 9mm. Is there any reason not to use 3N37 for 147 gr bullets? I seem to have found more data for the 124 gr bullets with this powder Any load suggestions etc would be great Joe Link to comment Share on other sites More sharing options...

Heavier bullets do better with faster burning powders. N320 is quite a bit faster than 3N37. Link to comment Share on other sites More sharing options...

I may save it for some 124 gr loads Link to comment Share on other sites More sharing options...
Desmo412 Posted October 3, 2012 Share Posted October 3, 2012 I'm sure it would work for 9-minor loads with 147s, but I think you will prefer the results with N320. I have used 3N37 with both 115s and 124s for 9Major loads with some success. If you are looking to work up some HOT loads for fun, 3N37 will do the trick Link to comment Share on other sites More sharing options...
