TimWarner Posted August 14, 2008 Share Posted August 14, 2008 Anyone have any ideas where to start for powder/loads with a 115gr MG bullet? Moving from 9mm to 38 and I'm not sure how to translate all the info I have. I assume a 9mm major load with the same bullet should be a decent starting point for 38 super/SC, but I have been wrong before. Link to comment Share on other sites More sharing options...
scirocco38s Posted August 15, 2008 Share Posted August 15, 2008 What powder? Link to comment Share on other sites More sharing options...
HSMITH Posted August 15, 2008 Share Posted August 15, 2008 Your 9 loads will be a good starting point, the longer OAL of Super will drop pressures and velocities a good bit. Link to comment Share on other sites More sharing options...
outerlimits Posted August 15, 2008 Share Posted August 15, 2008 8.3 of vvn350 gave me 1500 fps. wsr primers out of a 5" schueman barrel w/2 popple holes. Link to comment Share on other sites More sharing options...
G-ManBart Posted August 15, 2008 Share Posted August 15, 2008 Some loads that have worked for me (Bedell shorty with no popple holes). 10.0gr of VV 3N38 at 1.235" (169pf) 10.5gr of VV N105 at 1.245" (I have since shortened this to 1.230" with no significant change) 170pf. 8.2gr of VV N350 at 1.235" (168PF) Some that I have written down that others use, but haven't tried (no idea on oal). 8.5gr of VV 3N37 9.0gr of IMR 4756 8.1gr of Longshot 9.1gr of Tru Blu 8.1gr of IMR 7625 Link to comment Share on other sites More sharing options...
gm iprod Posted August 15, 2008 Share Posted August 15, 2008 I take it we should work on the theory that you are shooting USPSA. If so then the loads that G-ManBart gave you will work slendidly. If for Minor PF then look at the following. Win 231 / HP38 5.1gr Titegroup 4.8gr VV N320 4.7gr Link to comment Share on other sites More sharing options...
TimWarner Posted August 17, 2008 Author Share Posted August 17, 2008 Sorry, should have been more specific. For USPSA Major. Preferably non VV powder as it's hard to get around here, without buying a keg to test it out. Link to comment Share on other sites More sharing options...
JFlowers Posted August 17, 2008 Share Posted August 17, 2008 I am using 10.2 of VV3N38 with a 3 hole comp and two pop holes. But I run my gun a bit hotter than GMan, about 171-172 pf. Of all the powders I have tried so far I like VV3N38 the most, though I do have trouble getting it sometimes. Link to comment Share on other sites More sharing options...
TimWarner Posted August 17, 2008 Author Share Posted August 17, 2008 I can order VV powders online, but to make it worthwhile I gotta order a lot. Not economical for trying out powders. I'm probably going to start with my 9mm major load with HS-6 and work up. Link to comment Share on other sites More sharing options...

I've got a couple of friends who have been using HS-6 in 38SC and it's incredibly dirty....just nasty! We shot some of their ammo side-by-side with my old N350 load and they liked the N350 load a lot better. If availability is an issue I'd think hard about 4756 or Longshot as an easy experiment. My 'smith shot my new gun with 4756 and 121gr bullets and loved the way it reacted. Link to comment Share on other sites More sharing options...

Excellent availability and relatively cheap. I have been loading it in 38sc for more than a year now. Link to comment Share on other sites More sharing options...
TimWarner Posted August 17, 2008 Author Share Posted August 17, 2008 got a rough estimate of what you're using for silhouette? HS-6 is dirty, but If you run it at high enough pressure it turns out pretty clean. In 9mm anyway. Link to comment Share on other sites More sharing options...

My 'smith shot my new gun with 4756 and 121gr bullets and loved the way it reacted. 4756 works very well in my 4.5" gun, but it really fills the case and is a pain to load when you get over about 9 gr. You might try 7625, dot movement, for me, is not as nice as 4756, but much easier to load. Link to comment Share on other sites More sharing options...
uscbigdawg Posted August 18, 2008 Share Posted August 18, 2008 You can try the IMR powders as they're available in 1# lots. Yeah, VV is "expensive" but it's also easy to get rid of if you don't like it...'cause someone does. I used to run 115's and with N350 they're sweet.

In 9mm anyway. Silhouette is, IMO, as good as Vit 3N37 which is widely used in 38 S/SC. For 115 loads, I would start at 8.5. Silhouette burns really clean with a tight crimp and is a lot cooler than Vit 3N37. Link to comment Share on other sites More sharing options...
waynewal Posted August 21, 2008 Share Posted August 21, 2008 Sorry, should have been more specific. For USPSA Major.Preferably non VV powder as it's hard to get around here, without buying a keg to test it out. Have a Colt Govt model 70 from Jim Clark (20+ yrs old) one large hole comp, fully supported bbl. Worked up to 8.4 gr 4756 with a Speer 124 gr jhp (.355). Gives me around 1400 fps from my gun. Obvioulsy start lower and work up.... Search for 38 super here you will find a bunch of load data. Wayne Link to comment Share on other sites More sharing options...

Got Boost? Posted June 9, 2012 Share Posted June 9, 2012 I'm making 170 pf with a 124jhp and 7.2 gr. Autocomp. If I drop a 115jhp on it can I safely run AC up to major and what powder charge do you think I will need to get there? Link to comment Share on other sites More sharing options...
Got Boost? Posted June 9, 2012 Share Posted June 9, 2012 I'll throw 7.8 and go check it out! Link to comment Share on other sites More sharing options...
