Hello, New to the Forum,

Looking for load Data for H110 for a .357mag, using 158g LSWC. I have the Lee manual, but it gives no data for the 158g lead. Any help would be great.


Thanks RC

Uhh... That's kinda the wrong powder for lead bullets in a 357 mag. You're on my favorite bullet for 357 mag, but in my GP100, the magic load has been 5.1 gr Unique pushed by a CCI standard pistol primer.

That combo gives me one ragged hole at 10 yards, shot offhand.

H110 is not a flexible powder and will give you full power loads without the ability to reduce your load due to its being volume and load density sensitive. Don't download below the start load as that can result in a squib. You will need a hard bullet to avoid leading at the well over 1,000 fps velocities you will be driving them at but with the right bullet and fit they should shoot fine.

Here is some data for 158gr LSWC from the .357 mag load book. Good luck.

Lyman #49 says:

158 #358156 gas check:
15.0 start - 15.7 MAX.

160 LRN # 358311 plain base:
15.8 Start - 16.5 MAX

If these are store bought lead bullets, they may be too soft to push that hard with H-110 powder.

I would agree that Alliant Unique would be a better choice for mid-level velocity.
And Alliant 2400 would be a great choice too for max performance loads with lead bullets.
It is more forgiving then H-110 if you have to load down to prevent leading with store bought soft bullets. You can't load down with H-110.

Thanks, I am looking for the high impact loads. I just wanted to know if it was a load for the H110 with a LSWC 158g.

What would the hardness have to be to be in the safe range?
Is there a online bullet company that sells the hardness of bullets I would need?

I would like to get a load that gives the punch of a factory load but from my garage.

I have tried Blue dot, and 4227 IMR, neither gave the result I was looking for.

I want to stay safe, but want to know I can make a high power punch if I want one.

Thanks again, RC

I use and Oregon trail 158, with 2400, and a standard CCI primer this powder has given excellent results in my 357, when fired out of my flat-top blackhawk.

I`ve shot more than my share of swc with 15.0 grs. of h110 under em .

Light leadin (strippin not smearin) but I do cast my own & size em to .359 , good fit & a bhn of 15 or so & a premium lube is a must for shootin lead boolits.

I`ve switched to IMR 800x , cleaner, less flash .

MBC has a 158 gr SWC 18 BHN that I have pushed with 15.8 gr 4227 without leading after a tumble lube with Rooster Jacket. According to Lee that's 1,205 fps and 35,800 CUP. I don't know what pressure the H110 will give you, but they should work.

I am told the bullets I have are 18 BHN. This is from the manufacture. I have shot different factory rounds from all lead to JSP. I have the H110 powder, got it from a yard sale along with others un opened. Thought I could use it to max out the .357 .

Thanks RC

- Missouri Bullet Co 158gr LSWC 18BHN
- 16gr of H-110
- CCI #550 Magnum small pistol primers
- 1.595" OAL with a heavy crimp for consistent burn fits the crimp groove on these MBC's perfectly

My 2.25" SP101 eats these up all day long and asks for more. Although I do have a small amount of unburned powder with the short barrel, I've never had a single shred of leading when everyone tells me the base of the bullet should resemble an ice cream cone left out in the sun :P

You didn't say what kind of revolver you're shooting...the OAL on these works great in any SP101/GP100 I've tried them in but I believe it's too long for most S&W revolvers.

I've got the same question. I have a pound of H110 and a pound of IMR SR 4756. I was thinking of trying the 158 gr LSWC too. Either Missouri Bullet Co or Oregon Trail. I'm shootin' a 6" Ruger GP100. I have Winchester Small Pistol Primers and Magnum primers. I have 38 and 357 brass.

Any recommendations? Would the 4756 be any better than the H110 in terms of leading?

Any thoughts of the cost savings (LSWC vs JHP) vs the hassle of barrel leading and mess in reloading?

personally, I won't shoot any lead bullet over 1000 fps without a gas check...

NO, actually, thats exactly a great powder for 357 mag with hardcast lead bullets. He isnt looking for light loaded target loads, he said he is looking for hard hitting rounds.

personally, I won't shoot any lead bullet over 1000 fps without a gas check...

Why? I have loaded a Missouri Bullet 158gr LSWC(18bhn) loaded with h110. I didnt have lead problems. I currently load the same bullet over 14.5 or, if I am feeling froggy 15.0gr. No leading there either, and I am sure both are over 1000fps in a 4" 686.

2" barrel and H110 can be wastefull but if it is what you have then shoot em.

I have used 15 gr of H110 under my home cast 158gr Lee Tumble Lube water quenched wheel weight alloy and they shoot very well out of a 3" SP101 and a 6" GP100. They seem to bump up and seal just right and I only have slight smear leading after 100 or so.

I think in a 2" barrel you may get tired of this load pretty fast. I would like to suggest Bullseye, Unique, Clays, or HP38 for normal loads and 2400 or H110 for the heavy hitters. It works for me.

It's for the big bang, the little 2" shoots a tight group at 7 yards. A bit harder to group them at 10 yards, but you will get a few looks when you light that little sucker off. I also have an model 66 Taurus in .357mag, it will shoot nice groups out to 25 yards. That is all I can get at the range. I wanted something close to the factory loads I had been shooting, and the H110 worked up the best load.

If you want a good 158gr LSWC .357 Magnum load I highly suggest using HS-6. You will get the velocity you are looking for without excessive pressures or leading if you use the correct bullet. Don't forget to use a Magnum primer, I get much better results with a Magnum primer including single digit SD numbers.

Most of those were in .357 Mag and .44 Mag at 1200-1300 fps and some 9MM in the 1100-1200 fps range. When you get up in the 1400-1600 fps range gas checks become more desirable in some cases but I have a couple 1600+fps loads with plain base in .357 mag lever guns that do well.
