Hiroshi Posted September 3, 2018 Share Posted September 3, 2018 I want run major power factor on my open gun but I don't know what powder to use, I'm thinking going with these two powders. Your input much appreciated. 1. Vihtavuori N350 2. Winchester AutoComp Link to comment Share on other sites More sharing options...

chevrofreak Posted September 3, 2018 Share Posted September 3, 2018 I am a big fan of 8.3gr Silhouette under a 115 PD JHP at 1.150" these days. Link to comment Share on other sites More sharing options...
floater Posted September 3, 2018 Share Posted September 3, 2018 I have not pull the trigger on an open gun since 2005, but back then AA#7 and a 124 grain fmj in a 38 super was the sh#t! Link to comment Share on other sites More sharing options...
HI5-O Posted September 3, 2018 Share Posted September 3, 2018 HS-6 is working for me. Works in either 9 major or 38 Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted September 3, 2018 Share Posted September 3, 2018 HS6 is dirty but works well with 124 gr bullets, and WAC is cleaner and works well with 115 gr bullets Link to comment Share on other sites More sharing options...

TANFARM Posted September 3, 2018 Share Posted September 3, 2018 Limited my tests to HS-6 and WAC.....in my overall results the WAC preformed best for my needs . The case volume of HS-6 was a negative factor...spillage with my 650. Link to comment Share on other sites More sharing options...
EEH Posted September 3, 2018 Share Posted September 3, 2018 I put those little rubber washer from reloading innovations on my 650 and it really helped. Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted September 3, 2018 Share Posted September 3, 2018 1 hour ago, TANFARM said: The case volume of HS-6 was a negative factor...spillage with my 650. That's why I switched to WAC and 124 gr bullets. The 115 gr bullets under a whole case full of HS6 was a PITA to reload. Same reason I've never tried 3n38 - that's an even fuller case. If I ever thought that switching to 3n38 would improve my shooting ability, I guess I'd have to put up with loading very full cases - but, so far, I have no evidence to suggest that 3n38 would improve my shooting ability to any measurable degree ….

Stymie12000 Posted September 3, 2018 Share Posted September 3, 2018 #7 and 115gr bullet for me. Hs6 also worked well but accuracy wasn't as good as the #7. As stated before the #7 is dirty so you do need to clean often! Link to comment Share on other sites More sharing options...
OPENB Posted September 3, 2018 Share Posted September 3, 2018 When I shot a Super Comp, VV350 was popular, before 3n37 and 3n38 came out. As to 650 spillage, I cut a coil off the ball bearing spring and switched to a polymer ball, now the shell plate doesn't snap into place, Before that, I'd put the bullet on the case at station 3, and ride it over to station 4 to keep it from snapping in place. It was slower, but no spills. I started loading 9 major with WAC recently, and it works fine too. I picked up a pound of AA7 and will experiment with that soon.

Studlee Posted September 3, 2018 Share Posted September 3, 2018 Was using AutoComp for a while on a 124gr PD bullet. Earlier this year switched to CFE Pistol. Had to go .1gr higher charge than autocomp. For me recoil impulse was less and cleaner powder. Link to comment Share on other sites More sharing options...

speed Posted September 5, 2018 Share Posted September 5, 2018 (edited) imr 7625 (not made anymore) or auto comp Edited September 5, 2018 by speed Link to comment Share on other sites More sharing options...
MoonJeong Posted September 6, 2018 Share Posted September 6, 2018 The powder that always gives me the best accuracy regardless of pf- from 150 all the way to 180 has been aa7 and sp2. Hs6 comes next and autocomp comes in last. Autocomp is very accurate in a very limited range of pf in. It’s my open guns. Link to comment Share on other sites More sharing options...

Running a Lonewolf barrel. Very short throat. I have another LW barrel I had reemed out, but haven’t done this one. I’m sure I could open the throat, stretch it out a little, and get some more powder in there which may help the comp, but it works well for now.Sent from my iPad using Tapatalk Link to comment Share on other sites More sharing options...
