Dannix Posted January 6, 2012 Share Posted January 6, 2012 (edited) I enjoyed Silhouette when I was still shooting 115grn JRN. I got a quite accurate load out if it. I noticed some variableness though, and after reading more here, apparently it is reverse-temperature sensitive. Another power I was looking at for pushing 140grn cast boolits, WSF, apparently is reverse temperature sensitive as well. A powder I was looking at trying for non-warm loads, Solo 1k, is apparently reverse temperature sensitive. Is there any powder for 9x19 that's not particularly temperature dependent? I'm interested primarily in powders more applicable for warmer loads, but powders suitable for only minor loads are welcome as well. AA7? One of the VV powders? Thanks! Ultimately I'm looking for is a powder that will propel 140grn boolit to 1100fps, at below +P pressures, in a load that can hit a penny at 10yrds, with low flash and temperature resilient. Somehow I doubt I'll be able to check all those boxes, but I'm willing to be surprised. Edited January 6, 2012 by Dannix Quote Link to comment Share on other sites More sharing options...
JeremyM Posted January 6, 2012 Share Posted January 6, 2012 VV N310 or N320. My FPS varies +/- 10 from 35 to 110 degrees Quote Link to comment Share on other sites More sharing options...
Neomet Posted January 6, 2012 Share Posted January 6, 2012 VV 320. Very temperature neutral in my experience. Quote Link to comment Share on other sites More sharing options...
Dannix Posted January 6, 2012 Author Share Posted January 6, 2012 (edited) I thought I had seen N320 mentioned around. It looks like great option for a minor/slower load. Apparently it has a too fast burn-rate for a 1100fps load though. Edited January 6, 2012 by Dannix Quote Link to comment Share on other sites More sharing options...
mlmiller1 Posted January 6, 2012 Share Posted January 6, 2012 I believe v.v.3n37 is very stable plus it works well for "warm" loads in 9mm. MLM Quote Link to comment Share on other sites More sharing options...
rhyrlik Posted January 8, 2012 Share Posted January 8, 2012 If n320 is too fast, try N330. Quote Link to comment Share on other sites More sharing options...
Dannix Posted January 22, 2012 Author Share Posted January 22, 2012 Is AA#2 or AA#7 temperature sensitive, and if so, normal or reverse? I can't seem to find info concerning this. (I may just keep my own chrono records and compare come summer). Quote Link to comment Share on other sites More sharing options...
mda Posted January 22, 2012 Share Posted January 22, 2012 Pushing a 140 gn bullet at 1100 FPS in a 9mm and under +P pressure will be tough to do. Additioanl information would be heplfull, like what type of gun & barrel length. A longer barrel will be make it easier as you can use a slower burning powder to get there, as well as, loading slightly longer to keep pressure down some. All powders are tempature sensitive to some extent, after all it is a chemical reaction, but the Vit. powder is more stable then most. Try VV340 at about 4.0 to 4.5 gn.

9mmMike Posted January 23, 2012 Share Posted January 23, 2012 I chronographed HS6 in 9mm last week while temperatures were in the high 20's and had very consistent velocities across the board with different weight bullets and case manufacturers. I would say HS6 is insensitive, and non-tempermental. I also used some Accurate No. 5 and noted that it was consistent at lower temps as well.

blueeyedme Posted January 23, 2012 Share Posted January 23, 2012 If n320 is too fast, try N330. +1 I use N330 exclusively in 9mm. Quote Link to comment Share on other sites More sharing options...
hkguy Posted January 24, 2012 Share Posted January 24, 2012 ive had good luck with tightgroup for my 9mm loads. right now im shooting about a 133 pf out of my HK using 3.9 gr of tightgroup with a 124gr Berry's rsds. if i recall, the extreme spread was about 25fps for my loads too Quote Link to comment Share on other sites More sharing options...
Dannix Posted January 25, 2012 Author Share Posted January 25, 2012 Thanks all! mda, I'm ok with +P to an extent, but not too +P, at least not for every day plinking, and certainly not into Major territory. FN Hi Power Alloy with buffer and 18.5lb spring -- not something I would like to shot +P+ in, at least not to too great an extent. The Lee#2 manual has 147 Jacked AA#7 load at ~1050fps. I just got in a chrono so I'll start trying loads with 140gr lead shortly. I'll likely tone it down for accuracy sake and to save wear and tear on the gun, and am pickup a mold 125/130grn HP for greater fps loads. I load rounds that I may not shoot until over a year later, so temperature sensitive powders are less attractive for me than if I was competing.
