I don't know how Hodgdon calculates "burn rate" nor how closely my concept of burn rate correlates with theirs, but previous editions of their chart agreed with my real world data perfectly. Unfortunately their latest revision places HS6 on the faster side of the other popular 9 major powders which doesn't jive with my concept of burn rate nor my data. In my mind I group 9 major powders as fast, medium and slow: Fast (7ish grains for major with a 115): CFE Pistol Autocomp Silhouette Medium (8ish grains for major with a 115): HS6 Longshot Slow (9ish grains for major with a 115): SP2 3N38 These are just powders I've tested, but don't include: 3N37, N350, AA#5, AA#7, True Blue, etc. How was N350?, That's my next powder I want to try it out.

I've tried everything in the list, below the list are those I'm aware of, but haven't tried: 3N37, N350, AA#5, AA#7, True Blue, etc. Although now I can move AA7 up to the top, along with Lovex D037.1 (advertised as Shooters' World Major Pistol https://www.grafs.com/retail/catalog/product/productId/77203) both of which I think are excellent choices for 9 major on par with SP2 and 3N38. These powders take about 10gr to make major under a 115 and don't fill the case as high as 3N38. Edited September 8, 2018 by kneelingatlas Link to comment Share on other sites More sharing options...
Aircooled6racer Posted September 8, 2018 Share Posted September 8, 2018 Hello: For me to make major with Lovex DO37.1 with 115 jhp Montana Gold it takes 10.3 grains to make 171PF. 10 grains is only 158PF for my Schuemann 5" barrel. I don't think it shoots any softer than HS-7 at 171-173PF and it takes alot less powder. I have more testing to do with the Lovex powder. Thanks, Eric Link to comment Share on other sites More sharing options...

Knguyen1904 Posted September 10, 2018 Share Posted September 10, 2018 I prefer hs6 with 115s, autocomp works well too though. Link to comment Share on other sites More sharing options...

highhope Posted September 20, 2018 Share Posted September 20, 2018 My gun has 9 holes in the barrel. I load 8.5gr hs6, 124jhp, 1.165OAL to make 173PF, but it is not as flat as I want. So just bought 16lb Lovex DO37.1, try to get more gas to make it flatter.. Link to comment Share on other sites More sharing options...

Have you tried different recoil springs at that PF? That made quit a bit of difference on mine once I got PF in that range. Link to comment Share on other sites More sharing options...

Broncman Posted September 20, 2018 Share Posted September 20, 2018 (edited) Took an assortment of springs from 7-11 lbs, ran a couple Bill Drills at 10-20 yards. Anything above 9lb spring and spreads were horrible. 8lb springs gave me the fastest times and tightest groups. 8 lb variable kept them nice and tight. Heavier and the second shot would string vertically. I tried 165 to about 175 PF with HS6 and AA 7 with 7, 8,9 lb springs. Always came back to 8 lb springs and about 173-174 PF with HS6. AA7 was close second but powder spillage on the 650 even with the mods was annoying. Edited September 20, 2018 by Broncman Link to comment Share on other sites More sharing options...

quiller Posted October 1, 2018 Share Posted October 1, 2018 HS-6. My current load is Precision Delta's 124 JHP over 7.8 grains of HS-6 with an OAL of 1.145.....plunk test passed! Link to comment Share on other sites More sharing options...
Ray_Z Posted October 1, 2018 Share Posted October 1, 2018 HS-6 seems to be the powder of choice for 9mm major. But doesn't it burn awfully hot. Seems to me I tried that in 38sup and it had my gun so hot that I couldn't handle it after a couple of stages. It's been a long time since I loaded 38sup but I remember 9gr HS-6 and a 115 hp.

But I buy them at the gun rack in Kernersville 81 per 1200. Their website says like 243 for 3600. I’ve never been directly to there shop, is it cheaper? I’d imagine it is cutting out the middle man. Ive had zero leading also in 9 major. Their coating isn’t the thin hi tek, it’s like a thick polymer jacket. Very clean in my guns. Link to comment Share on other sites More sharing options...

I agree, it is very hot. Try changing recoil springs after shooting 100rds. Pain in the ass. Had to do it this weekend. Link to comment Share on other sites More sharing options...
Posvar Posted October 3, 2018 Share Posted October 3, 2018 I’m using HS6 and like it a lot. It does get hot though as stated above. Has anyone tried N340 with 124 grain jacketed hollow point bullets? I came across about 13 pounds and Johnny Lim says it’s really really good. I have not used it yet. Link to comment Share on other sites More sharing options...

Find a local guy to use a 5% off code or I think BENOS is a coupon code too on their website. Maybe I was a few bucks off on $220, more like $230 Edited October 4, 2018 by sstephns Link to comment Share on other sites More sharing options...
KrisS Posted October 9, 2018 Share Posted October 9, 2018 I have two loads I am using with Bul SAS II UR Open 9mm 1. Bullet : LOS 123gn RN (copper plated), Powder: Vectan SP2 8,65 gn OAL 30,0mm (1.181) PF 162-167 depending of weather 2. Bullet : LOS 123gn RN (copper plated), Powder: VV3n38 8,05 gn OAL 30,0mm (1.181) PF 162-167 depending of weather Vectan SP2 gives more gas and compensator works very nice, it is quite clean but measuring it is very demanding. VV3N38 is even cleaner than Sp2 and softer in recoil very easy to measure still the 9mm case is almost full with 123gn bullet. Next powder for my elaboration will be Lovex D037.1 which is even more dense than SP2 and is cheaper and easily available in my country. Link to comment Share on other sites More sharing options...
cconnection Posted October 16, 2018 Share Posted October 16, 2018 I am a fan of the Winchester Auto-comp. I have a new svi 9mm barrel and can make major power with 6.6 gr with a 124 Jacketed round PD bullet. Does not seem to make sense to me to use a powder that you have to get up over 9 gn. to make Power, am I missing something? Link to comment Share on other sites More sharing options...
