Default Huge difference in 357 mag load data

I picked up some Remington 158gr SJHPís and Iím looking to load them with H110. I have compared 4 books and Iím having a hard time choosing a starting point. I normally use the data put out by the bullet manufacturer but in this case there is no data. Below is the data in my books. Iím thinking of starting at 14.9 and working my way up.

Hodgdon start 15gr to 16.7max
Nosler start 14.9 to 15.9max
Hornady start 12.7 to 15.6max
Lyman 49th start 16.3 to 17max

I'd do four steps for the first ladder: 15.1, 15.4, 15.7, & 16.

Yes, look at it this way. If you start low and work up what is the harm? All guns, reloading supplies, and powder has some variation - even your reloading. So just work up and look for pressure signs along the way.

In 8 yrs of reloading, I've found thst starting at the minimum load is usually a waste of time and components.

Not very accurate, some guns don't cycle (revolvers exempt!), and the overall experience is like kissing your sister-not very enjoyable or productive.

I plan on just doing 10 of each up to max. I’ll be shooting these in a Taurus snubnose 357. They are mainly for fun and a big flame. My friend who is also loading the ammo with be shooting them through his ruger Blackhawk which I know will have no problem with the loads. I’m just iffy on the Taurus. It’s not as built like a tank as his Blackhawk.

H110 is a relatively slow burner on the pistol powder spectrum. In the snubby taurus you won't get max pressures in these load ranges. Pobably the most discernable difference between load increments will be the size and length of the flame front out of the barrel as a lot of powder is going to be blown out the muzzle as it burns.

Doesn't look Yuge to me. 1 gr?

Different labs, different powder lots, different primers (and lots), different bullets..........

Common wisdom is H110 can be dangerous when downloaded. Personally, I think that's poppycock invented as a solution to other problems.

Normally with pistol powders most sources are close. Just have never seen a difference like this. I also read about the h110 being downloaded and that was my concern. Gonna load them up tonight.

H110 used to say not to download more than 5%. W296 used to say 10% IIRC.

Note the H data you posted is an appx 10% spread. Start at the bottom and watch for for fps and pressure signs. I can flatten 357 primers with book data, so do pay attention.

I use Hodgdon data and still have all my fingers.

I just couldnít figure out why hornady loads were much lower.

I'm not looking at a bunch of data at the moment, but I still say it doesn't seem yuge to me. Not with a slow burning powder requiring in the 16 gr. range.

There's also a difference in era. Newer data tend to be more conservative.

I run about 15.5 gr of h110. Ymmv. 586 and 686 both 6 inch barrels.
And yes you will get flames.

Your right. I didnít think in terms of the short barrel and slow burning powder.

On a second note what powder would get me the best velocity with such a short barrel? I also have some 110’s I’m gonna load up too.

If you give me your specific bullet length and your OAL and your barrel length, I can better tune Quickload, but here is what Quickload says for a generic 158 JHP:

Code:
Cartridge          : .357 Magnum (SAAMI)
Bullet             : .357, 158, Lapua SJHP EG410
Useable Case Capaci: 16.354 grain H2O = 1.062 cm≥
Cartridge O.A.L. L6: 1.590 inch = 40.39 mm
Barrel Length      : 6.0 inch = 152.4 mm
Powder             : Hodgdon H110

Predicted data by increasing and decreasing the given charge,
incremented in steps of 1.25% of nominal charge.

Lee: XTP: 15-16.7.

I really need to chrono some PMC 158gr SJHP, full house loads for comparison to what I load plated to...

You could try 2400. Far more forgiving than H-110.
