357 magnum powders other than 2400 110/296

Longshot is close to full magnum vels, not quite there but close. I have seen some around lately. Also works well for medium-heavy to heavy 9mm, and heavy 45 ACP. Others say it works well in 40 and 10mm also., but I don't own either so I can verify that.

Longshot is loud as well if you like noise......Loudshot
 
My entire world of magnum revolver has been with jacketed bullets and full throttle powders, so maybe I can help shed a bit of light on this for you.

If I remember correctly, the first powder I used for .357 mag. was Blue Dot. I used it for a few years before switching to H110/296. It produced good full throttle loads, but not quite as stout as H110/296 has for me. Seemed clean and produced good consistent velocities though, good stuff.

And another good one is AA9, this powder has performed very well also, but still a bit lighter results compared to H110/296, not enough to make much of a practical difference though, it still produces good full pressure loads IMO. AA9 seemed a bit cleaner than Blue Dot, I really liked it, but haven't noticed it around in a while, but that might just be because I wasn't looking for it.

Blue Dot only worked with jacketed bullets, it badly leaded with cast bullets. Accurate Arms #9 is a good magnum pistol powder, shot well, hardly any leading. The absolute best magnum powder is one you don't want to hear about: W296/H110.

Yes! Lee #2 shows 6.5 gr. pushing 158 gr. lead at 1,320 fps.

Lee only borrows published data...

That load is directly from the old paper Alliant manuals (pre Speer merger)...It shows pressure to be 33,900psi...

Buy a chronograph and get back to me on that. While you're at it get some pressure tested data from this century. Alliant's latest data with Bullseye in 357 Magnum with a 158gr LSWC is a max charge of 4.8gr for 939fps. Hardly a magnum load. Even Lyman's 49th Edition 155gr LSWC (#358156) 7.0gr max load of Bullseye barely breaks 1100fps. Their start load of H110 is over 1300fps. None of the major jacketed bullet manufacturers publish data using Bullseye with their bullets in 357 Magnum. Bullseye is not a magnum powder in the same category as 2400 and H110/296.
 
I got "lucky" today well, with luck being a rather relative term. I found some H110 and N110 finally while out and about in another town.
I had to give up $40 for the H110. Yeah it hurt, but at least now I have something to play with for the summer. perhaps I'll find more in the coming months. I see that recobs has 300mp in stock still too. might try and add up enough to make something doable there

They wanted $56 for the VV110. I passed that was just too much hurt without the can coming with a free tube of vaseline.

My test batch with BE-86 is ready to go, and I will be revisiting by can of Blue dot as well.

For those that are curious, I'm not a velocity hound - I do realize the relationship between accuracy and speed. But I have what I consider my pet loads in the 1000 fps range, and am looking to fill out my 'chart" as it were trying to create reloads that approach or exceed commercial loads. Save for the Buffalo bore loads. I don't know what they load those things with, but the first time I let one go at the range, I heard a guy 2 tables over say "Dayuum" I've also never made the higher velocity magnums before and I've got the itch to make some. Speed isn't everything, but my 800 fps target loads don't get to the 100 yard gong without about 2 feet of holdover, lol.

This, is why I want to play with the longer range stuff:

it's just screaming for long range work

A criteria that is important to me is low to moderate density, resulting in good case fill, which the magnum specialty powders generally provide.


BTW 2400 is not that radical. Good choice though.

2400 is the original and classic magnum handgun powder. I don't know that I would use the term radical to describe any of them, but 2400 will come very close to the velocity of any of the others all whole having a much better loading range and not requiring magnum primers.

Sorry you needed to parse the word radical or infer that a revered powder was being disrespected. What I had in mind when using the word radical is a load that I wouldn't shoot in a smaller carry gun. According to my references, 2400 does not generate the high end numbers that some more modern magnum specialty powders do.
 
All the powders that are "close" are always good to know about but I keep using H110/W296 because of the velocity, flame temp and the standard deviation is 12 fps in my handloads and in Winchester White Box.
 
Hodgdon Lil Gun, best I have used in my Ruger Securitysix. Less felt recoil for the same velocity as other brands, and clean burning and accurate.

"Flamable Dirt" (Unique) is NOT allowed anywhere near my guns...... Makes a fair fertilizer though.

I'm sorry that you are offended by my posting. There isn't much to be gained by using powders like 296/110 over 2400. To each their own, I could certainly care less what others want to put in their cases.
 
If you are just loading for handguns the velocity or "return" on your powder "investment" is actually really quite terrible for these so called magnum powders.

In a nutshell you are burning twice as much powder to get 20% more velocity if that. Using the greater powder volume really only becomes beneficial in carbine length bbls.

I personally like hs6 for my "magnum enough" 357 loads.

I was always ambivalent about 357 powders, probably favored H110/296 until I tried VV N-110( hey 7mmb) which I had gotten for my muzzle loader. It is so much an improvement over most other powders I can't see going back. Its more pricey than other stuff, but if yer talking about 400 loads to a pound, lets be serious thats only a penny or so. Inflation on bullets or primers every week is more than that. It works well with cast or jacketed bullets, the velocities are not as high as some of the fireball powders, but we're talking about 50 or so FPS. Shoots very clean and the accuracy is first rate. Works like a champ in the 45LC as well. I seem to be able to get it from my LGS most of the time. I keep a couple of pounds in reserve ever since the BoBo inspired shortages started.
