Tree Rat Posted October 10, 2002 Share Posted October 10, 2002 How come most references list 3N37 as faster than N350 when in most loadings it allows for greater max charges at near equal velocity?? TR Link to comment Share on other sites More sharing options...
ErikW Posted October 10, 2002 Share Posted October 10, 2002 'cause burn rate isn't the end-all/be-all factor determining pressure (?) Link to comment Share on other sites More sharing options...
BrianH Posted October 11, 2002 Share Posted October 11, 2002 I'm imagining this being like the WW540 v.s. Hogden HS-7 thing.....I get a similar feeling when I shoot them in super, too. Although to me 3N37 doesn't snap like 540. Makes major nice, though. Talking to a friend of mine about this recently, he said he shot 350 simply for the reason that it cronoed more consistently than 3N....in HIS guns. Most else does seem similar, but I'm using 3N37 because the pressure/recoil/boom/reliability seems to be perfect for the velocities Im getting...and consistent as hell...in MY gun.....

kbear38S Posted October 11, 2002 Share Posted October 11, 2002 he said he shot 350 simply for the reason that it cronoed more consistently than 3N.... in HIS guns. And to illustrate the importance of that statement, at the Area 8 using 3n37 my gun chrono'd 1501, 1499, and 1502. The same ammo in my wife's gun had the same low deviation. Amazing thing is I was using used brass though all the same brand. Link to comment Share on other sites More sharing options...
ErikW Posted October 11, 2002 Share Posted October 11, 2002 Yeah my 3N37 loads did the same thing last year at the B2B nats. I just shot the last of my N350 loads and I'm down to a couple pounds of 3N37. When I run out I think I'll stick to N350. Can't notice a difference shooting, but it's cleaner, just a hint of soot. 3N37 kinds of gums up in the Kellube. And I use less powder with N350.

kbear38S Posted October 12, 2002 Share Posted October 12, 2002 I just changed to 3n37 from IMR 7625. One thing I just noticed is some residue - almost looks like dirt got in the breech area. It's not just carbon soot like I got with the IMR, its more of a grit. Is this typical? I tried some N350 and it's great with 125s but the muzzle flash seemed excessive with 115s. I could see it in bright sunlight and in the evening, it's overwhelming. Link to comment Share on other sites More sharing options...
ErikW Posted October 14, 2002 Share Posted October 14, 2002 Yeah 3N37 is infamous for its little yellow cornmeal grit, a la AA #7. I get much less (almost none) in Super than I did with .40 S&W. I also notice some ash-like particles left over after cleaning. Link to comment Share on other sites More sharing options...
