Win 296 for 357 mag

[357smallbore]

I love this powder for my Security Six and GP 100.
Anyone out there load their 357s with this powder?

 

[newfalguy101]

I will....eventually when I get my reloading setup....set-up

 

[ArchAngelCD]

I have been using W296/H110 in the .357 Magnum for a very long time. I highly recommend using a magnum primer with W296.

 

[JimKirk]

Yeah ... .357 Mag, 41 Mag & .44 Mag...

 

[Blue68f100]

Yes, since the 70's. Like said, use a Mag Primer is required.

 

[Riomouse911]

And follow loading manuals closely and don't drop below minimums, 296/H110 is one of the powders that doesn't like to be downloaded.

Stay safe!

Also remember a good firm roll crimp. From someone who has been using it (along with its twin H-110), since it came in steel containers and cost less than $10 per pound.

 

[LoonWulf]

I've only used it in .357, from a 16" lever gun, but it worked well in that application.

I also run it in .44mag, and used to use it in my .458 Socom.

 

[troy fairweather]

yup great for 357 mag and 44 mag. don't down load it. use a heavy crimp and a magnum primer. if you stick to these 3 rules it will make a good load.

H110/W296 is an excellent full power, magnum powder in the 357. I am of the opinion 2400 is more flexible because you can reduce the powder level with 2400 to a certain extent, H110/W296 cannot be reduced according to the manufacturer. Nevertheless, H110/W296 produces good velocities with excellent accuracy

W296/H110 is only really good for one thing, Full Power loads but it does those really well.
If that's what your after it's good stuff!

 

[doubleh]

I've used it since I bought my first .357 back in the late '70's. Good stuff.

 

[Patocazador]

I've never used it in .357 but it's my 'go-to' powder for .44 mag and .44 auto mag. It really cranks up the velocity.

 

[Z28roc]

I use 296 / H110 occasionally. Sometimes you just need that big full house bang in a handgun. But I really love them in my Henry rifle. Now that's music!

I've found that I like Power Pistol as a good compromise between power and accuracy in a handgun.

 

[Hooda Thunkit]

I have worked up some loads in a 6.5" Ruger Blackhawk. I don't shoot a bunch of them, no need.

I do however, recommend both earplugs AND muffs when shooting those full power loads. Something about the CRACK of those rounds really pierces my ears.

 

[Jonesy814]

Yep! My avatar picture is 21gr of Win 296 under a 125gr XTP
Here are some dusk shots with a 2.5 inch 686 and more 125gr XTPs loaded with 21g

 

[Obturation]

Yeah, i burn through a mountain of 296/h110 per year. Its good stuff. For 357 mag i get better accuracy with 2400 and 158 swc but i still use h110 quite a bit too. For 454 casull h110 is the best there is.

I used 110 gr Sierra HP and H110. It was amazing. I never got a picture like that.
Flame cutting is an issue with these loads.
I now prefer H110 and a 158 or 180.

 

[Orcon]

Oh sure, 16 grains and a 158gr XTP. Is it necessary? No. But is it fun to shoot? Also no. It's my go to load for reminding me that I'm not as much of a bad-ass as I think I am.

16.7 and we're golden! Or 22.0gr behind a 125XTP. 1352fps and 1717fps, respectively, from my 6" GP100 at the last chrono session. I used to flinch almighty with such loads, but shooting them for a few years consistently has really improved my technique. When I go back to a 9mm now it's like shooting a 22.

 

[Jonesy814]

My regular plinking load for 357 is 15 grains under a 158gr Hi-Tek coated, cast bullet. Works good, and you know you are shooting magnums but doesn't shake the gun or shooter apart

 

[mikey98e]

I love this powder for my Security Six and GP 100.
Anyone out there load their 357s with this powder?

Yep been using it for 40 years in my 357 loads.
18.5 gr with a 140 gr Hornady XTP or 16.5 gr with a 158 gr Speer JSP
(The Speer for 40 years, the Hornady for 3 years)

That 16.5 charge worked for every 158 jacketed bullet I tried.
I've never used a 140, what caused you to pick that over a 125 or 158?

 

[Laphroaig]

Its a great powder for 30 Carbine too, for those of us that load both.

 

[Charlie98]

Yeah ... .357 Mag, 41 Mag & .44 Mag...

Only the .41Mag for me, and only in my big Dan Wesson, or in the 20" barrel of the Marlin 1894, with JSP's or the 250grn Cast Performance bullet... Never used it in .357, however, and I don't have a .44. I consider it a specialty powder, normally I don't need all that speed and noise.
