Naka16 Posted December 22, 2013 Share Posted December 22, 2013 I know that 3n37 may not be the most desirable powder for minor loads, but is it possible to get down to the 135-140 pf range? I got close to 15lbs left and I wanted to use it up. Thanks in advance Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted December 22, 2013 Share Posted December 22, 2013 Might be possible to trade it to someone with an Open gun who desparetly needs some 3N37. You might be able to get your hands on some N320 or WW231, which would be better for you. Link to comment Share on other sites More sharing options...
Naka16 Posted December 22, 2013 Author Share Posted December 22, 2013 Thanks, would red dot work for 9mm? I found two pounds that I could use. I'm guessing it won't meter well in the dillon powder measure. I bought the 3n37 for my open gun project in .40. Link to comment Share on other sites More sharing options...
BeerBaron Posted December 22, 2013 Share Posted December 22, 2013 red dot will work but it's the opposite end of the scale (too fast burning). it's equivalent to a powder here called AS30 which is a shotgun powder but it can be used in 9mm minor. The hassle is it's such a small load both by weight (in the 2.5gn range) and by case volume. makes it dangerously easy to miss a double charge (depending on press of course). it can also be a bit inconsistent. the 3n is a bit too slow burning to be useful in a 9mm minor load. here's a table that may help (it's put out by the aussie company ADI that produce hodgdon's powder among others). powders start fastest burning up the top and get slower as you go down the table right up into rifle powders. http://www.adi-powders.com.au/handloaders-guide/equivalents.asp some popular US powders are missing unfortunately but many are on there. As a guide in australia AP100 is very popular open gun powder. and even it is a bit faster than 3n37, ideally you'd want to swap for some N320 or even N330. but in a pinch the red dot is probably better to use than the 3n37.

Rick88 Posted December 22, 2013 Share Posted December 22, 2013 Try the 3n37 first it might surprise you, sometimes we need to think outside of the box. I had some left over 3n38 that I wanted to try for minor 9mm and thought no way, even if it did work it would suck. Well turns out I was very wrong I couldnt find any data at all so that scared me a bit so I loaded very lite at first, the gun wouldnt even cycle so I kept bumping it up a little at a time until It was throwing the brass about 3 ft with no issues. It feels fantastic and is single hole accurate this isnt supposed to happen going by the charts but it is what it is... Link to comment Share on other sites More sharing options...
Pasley Posted December 23, 2013 Share Posted December 23, 2013 My Speer # 13 has 3n37 data for the 124 grain Gold Dot.. 1063 fps to 1179 fps. I feel like it is at least a reasonable powder choice if they published the data. If I understand correctly a 124 grain bullet at 1100 fps would be a 136 power factor?

What does speer have as a starting load? Are the gold dots plated bullets? Link to comment Share on other sites More sharing options...

Pasley Posted December 23, 2013 Share Posted December 23, 2013 The Gold Dot is a jacketed hollow point. Speer lists a start load of 5.7 grains and a max of 6.4. OAL at 1.120 Link to comment Share on other sites More sharing options...

This makes me wonder what the actual difference is between the two powders. Link to comment Share on other sites More sharing options...
Pasley Posted December 23, 2013 Share Posted December 23, 2013 No data in any of my manuals for 3n38. If you look at the data here for the .40 S&W I think we can extrapolate that 3n38 is a good bit slower than 3n37. http://www.lapua.com/en/products/reloading/vihtavuori-reloading-data/relodata/6/25 I have loaded a bunch of 9mm with n340 and think that works very well.

truborshooter Posted December 23, 2013 Share Posted December 23, 2013 http://www.lapua.com/en/products/reloading/vihtavuori-reloading-data/relodata/6/34 increasing oal will decrease pressure and speed Link to comment Share on other sites More sharing options...
