okorpheus Posted February 15, 2013 Share Posted February 15, 2013 Just wondering which way WSF reacts to high or low temps if at all. Sent from my iPad using Tapatalk HD Link to comment Share on other sites More sharing options...
yoshidaex Posted February 15, 2013 Share Posted February 15, 2013 Gets faster when it's colder Link to comment Share on other sites More sharing options...
COF Posted February 15, 2013 Share Posted February 15, 2013 WST is the same way Link to comment Share on other sites More sharing options...
yoshidaex Posted February 15, 2013 Share Posted February 15, 2013 My bad. I haven't used WSF in varying temps. I used it once and didn't like it for my application. Link to comment Share on other sites More sharing options...
Histate Posted February 15, 2013 Share Posted February 15, 2013 Need some feed back from you WSF users I'm loading 9mm and 45acp I've been using w231. If you are loading for both calibers how does this powder work out for you pros & cons thanks Link to comment Share on other sites More sharing options...
HoMiE Posted February 16, 2013 Share Posted February 16, 2013 WSF isn't reverse temp sensitive like WST. As far as WSF v W231, it takes a couple of tenths grain more for same velocity but WSF is a lot cleaner than 231. Either works well with 9 or 45, I preferred WSF as it is bulkier than 231 and filled case more and easier to see in case and make sure you didn't have a double charge.

freakshow10mm Posted February 16, 2013 Share Posted February 16, 2013 WSF isn't reverse temp sensitive like WST. That is a false statement. WSF is reverse temperature sensitive just like WST. Both powders increase velocity when cold and decrease velocity when warm. Link to comment Share on other sites More sharing options...

Good to know what type of temp change are you talking about to notice a difference I live in Hawaii so temp doesn't really change or vary to much maybe 15 degrees at the most. Temp around here is 70-85 degrees Link to comment Share on other sites More sharing options...
freakshow10mm Posted February 16, 2013 Share Posted February 16, 2013 As in summer versus winter in the Midwest. 20F versus 80F. Link to comment Share on other sites More sharing options...
Histate Posted February 17, 2013 Share Posted February 17, 2013 Well I don't have to worry about temp sensitive powders then, I guess I'll give wsf a try Link to comment Share on other sites More sharing options...
bishop414 Posted January 6, 2014 Share Posted January 6, 2014 Bringing this back up for my education. How much velocity drop or increase per change in temperature? Right now, working up loads at 65 to 70 degrees but knowing I will be shooting in 105 - 110 as well. Guess the question, is a 40 degree swing enough to worry about or you won't notice?

dlfleetw Posted January 7, 2014 Share Posted January 7, 2014 As a reference, I worked up a load of 5.3 gr behind a BBI Moly 180 hr at 1.180 going about 940 fps out of my Trojan .40 at 80 degrees. I shot that same load at 45 degrees and saw a 10 shot average shooting 947 fps. Same location just different time of year. I have since bumped my load to 5.4 gr to cover temp and Chrono variance. I did load some at 5.6 gr and saw about 990-1010 fps out of the same gun at the lower temp. Link to comment Share on other sites More sharing options...
