ParaGunner Posted September 11, 2019 Share Posted September 11, 2019 I've tried this question in the 9/38 reloading forum with no reply for weeks. So, has anyone tried imr blue for open major and have any data? Link to comment Share on other sites More sharing options...
Glk21C Posted September 12, 2019 Share Posted September 12, 2019 I tried it, it worked but I like vv350 better. In my open gun(38sc) it took over 9 grains to make major with 124/125 grain bullets. Not saying it’s a lot of powder, there was still room in the case, just took at least that much. TruBlue seemed to be the same powder with the same results. i was more curious to see would it be viable to use if I couldn’t get vv as imr blue or trublue I could find locally good luck Link to comment Share on other sites More sharing options...
ParaGunner Posted September 12, 2019 Author Share Posted September 12, 2019 (edited) Of the 2 powders I've tried so far, (autocomp-8grns and aa7-10.8grns to make major with 124grn bullet) I'm trying to find a powder in the middle of those two. Did the imr blue meter well or does it fall out everywhere like aa7? Aa7 is so fine it leaks out of my powder bar on my Dillon and gets everywhere. 15 minutes ago, Glk21C said: I tried it, it worked but I like vv350 better.

If so how many? My sv has 4 along with the comp. Link to comment Share on other sites More sharing options...

ParaGunner Posted September 18, 2019 Author Share Posted September 18, 2019 Finally found a pound of Imr blue locally to try. Didn't really work out in my 5" SV with 4 barrel holes and comp. 10.5 grains of blue filled the 38sc case to the top and I only got 1290 FPS with 124grn bullet. It seems blue is slower than Aa7. I can make major with 10.8grns of Aa7, but it spills everywhere on my press out of the powder dispenser when I use it. I might try Silhouette next.

racer-x Posted September 18, 2019 Share Posted September 18, 2019 Try this with your powder bar to minimize spilling with fine powders like AA7. AA7 is a great powder for 9major and this makes loading it a lot less messy. Link to comment Share on other sites More sharing options...

I'm shooting 38sc and I have 4 barrel holes. It takes extra of any powder for me to make major. Link to comment Share on other sites More sharing options...

I don't see why it wouldn't work for you. The working parts of the SDB powder measure looks just like my 550 & 1050 powder measures. The point of the tape is to reduce the slop in the moving parts where the powder slips through. Add more or less tape thickness to get it slop free, but still non-binding.
