If you could only use one powder for loading the 357Sig what powder would you choose and why?
Probably long shot. It meters well, attains near max vel with much less powder than aa#9, which would be my other choice. AA#7 would come in 3rd for me.
Not even a difficult choice Hodgdons Longshot. SJ 40
Excellent results over the last 10 years or so with Power Pistol and AA#9.
AA#9, no question about it. You can run it down to the point where the slide just cycles and you still get incredible consistency and clean burning. The ballistic consistency with this powder in the .357 sig surpasses that of any other pistol caliber/powder combination (although WST in the .45 acp gives it a run for the money).
Definite safety advantages in terms of preventing bullet setback.
Has anybody tried H-108, its between AA#9 and H-110.
...HS-6, as it has VERY low muzzleflash, and that's important for PD rounds. Longshot and A9 are high-flash powders. See http://www.ozarkmtns.com/foliage/index.asp for the results of my research.
And I have about 20 pounds of it, having been smart enough to buy 2 8-pounders a couple years ago after I fell in love with it and the supply of powder was getting tight.
Goosedowner, live anywhere near Phoenix?
I like Blue Dot, since I've lost a lot of hearing anyway playing drums, guitars, and serving onboard a few Navy boats
jeffreybehr, sorry but I live in Pa.
I just talked to the local Sporting goods store (only good one with in an hour drive) and he said I could forget about getting any Hodgdon powders for a while. The only powder he has that's been talked about here is longshot.
He did say that he has a lot of VV N-105. I LOVED the VV powders when I was shooting competition with a 40!!
Anyone ever load N-105 and if so how did you like it?
VV105 should work, but the LS is half price, will do fine.
I agree with Longshot. AA7 and 9 are fine, but LS is more economical.
Honestly, but for VV powders, cost of the powder charge in any handgun round is just not a deciding factor for me. TG or LS in the 357sig @ the same vel, 1/3 of a penny diff per round. With primers & bullets taking the lions share, choose a powder for the performance, never for the cost.
If Longshot can't be found I would look for Power Pistol or Blue Dot as other choices. SJ 40
I primarily use Power Pistol for range loads however I also use HS-6. If I had to choose between the two I would choose the HS-6 because of the low muzzle flash, PP is a very flashy powder. The HS-6 also works will with light bullets to heavy bullets like the Power Pistol but load data for HS-6 seems more available.
Another vote for Longshot.
First choice, Power Pistol, second, Longshot.
Hs7 was my fav, but no longer made. Maybe I should try some hs6, if I could ever find any.
