SRT Driver Posted December 28, 2004 Share Posted December 28, 2004 Been using 4.1 of N320 for Production at 136pf (1090 fps with a 125 Zero). It is a decent load but just picked up a 4lb can of N330 since 320 is getting scarce. Does anyone have any ideas for a 124 - 125 gr bullet? (too cheap for 147's ) The book says 5 gr for about 1125fps. My thought is 4.8 or so. Does it burn well at this level etc? Thanks. Link to comment Share on other sites More sharing options...
ErikW Posted December 29, 2004 Share Posted December 29, 2004 I just loaded a bunch of 124 JHP with N330. Problem is my newest jug of 330 is much hotter than my previous jug, so I'll say you shouldn't take any shortcuts and work up from the starting load in the booklet. It's clean, accurate, and makes good velocity. Side-by-side, you might find N320 a little softer at the same velocity. Link to comment Share on other sites More sharing options...
MoNsTeR Posted December 29, 2004 Share Posted December 29, 2004 I found N330 to not burn clean, even up to listed max, in 9mm/124gr. It threw soot all over my arms with 3 different guns. Link to comment Share on other sites More sharing options...
SRT Driver Posted December 30, 2004 Author Share Posted December 30, 2004 Thanks Eric / Monster, I'm going to start with 5.1 and see. Interesting about the soot. I get a little bit with N320 too. 9 seems to be the only caliber I get soot with N320. I'm going to chrono on Fri night. Thanks. Link to comment Share on other sites More sharing options...
SRT Driver Posted January 2, 2005 Author Share Posted January 2, 2005 Chronoed on Fri: 5.1 N330, Zero 125 JHP, 1.11 OAL AV = 1152 FPS PF = 144 4.9 N330, Zero 125 JHP, 1.11 OAL Av = 1105 FPS PF = 138.1 4.1 N320, Zero 125 JHP, 1.11 OAL AV = 1086 FPS PF = 135.7 In a Glock 34. The N320 load felt softer, 4.9 N330 was a little snappier but not bad. 5.1 of N330 felt like WinClean 124's. Link to comment Share on other sites More sharing options...
gm iprod Posted January 3, 2005 Share Posted January 3, 2005 SRT, Try Hodgdon TG at 4.0gr. Should be bang on 1040fps (130pf). I have gone as low as 3.8gr and a 5" barrel and got 1010fps (126.25pf). But only if you KNOW it will stay at that regardless of the weather. Not as clean as N320 ( but still very good ) but easier to get where you are and a trainload cheaper. See ya.
