H110 has a very narrow loading range in .357 from my experimenting. Like about 1.3 Gr TOTAL.

I used 2400 for 357, it’s a little dirty but loads well. I also used BE86 in the last year or so. Nice and clean with a little snap. You can not go wrong with either.

I've been reloading since 2001, (9, 40, 45, 223, 300blk, 308). I just bought 38/357 dies and last week I found out about lite loads of H-110 for 357. That low power load will not burn completely by the time the bullet passes the gap and will fizzle out. Set that powder aside and tried 4227 for 38, loaded some different loads but yet to test them.
People have blown up guns with light loads of H110/W296, exact same powder other than lot to lot differences. I personally don't like that powder due to how sensitive it is to temperature. I would never use it if you can't have a safe load at 90% or greater fill density. If you use it and you develop loads when the temperature is hot, and your rounds have been in the heat long enough to stabilize, you are safe to shoot in lower temps. Never do in the other direction.

Does anyone know if the 15-2 with 8" barrel tends to prefer one weight or manufacturer' bullet? I shot some 158 gr. Sierra JHC sitting on 14.3 gr. H110. Flash seemed excessive when indoors and the burn was not very clean. Velocities were very close to the Hornady data. I have more Sierra 158 gr. JHC, some Sierra 140 gr. JHC, and Hornady 158 gr. XTP. The ultimate goal is a good hunting load.

All I use are Zero 158 gr JSPs or JHPs over 2400 powder👌🏻
1.5" groups in my scoped 715 8 inch at 100 yards

That’s good groups, especially for a pistol at that distance.

Let me start out by saying that I am working with what I have in my stash or what bullets I can find locally. Most shooting is indoors at 25 yards and I am using data from 357 Mag LoadMAP and Hornady reloading app. Best groups are 140 grain Sierra JHC or Hornady XTP over 17.9 or 18.0 grains of H110. I am getting decent results (but I want better) with 14.8 to 15.2 grains H110 with 158 grain Sierra JHC or Hornady XTP bullets. Bullet brands and head stamps don't seem to significantly change accuracy, velocity, ES or SD. Cases are nickel with mixed head stamp, unknown number of firings, and probably 5-10% split every range session. I suspect most deviation is due to neck tension which is evident when extracting the powder funnel. I am holding my brass cases in reserve right now but they are also mixed head stamp, unknown firings. Now for the questions:
1. What are the opinions on nickel cases? Use them, can them, anneal them?
2. How about head stamp brands? Best or worst brand?
3. Best SPM primers? I am using old CCI SPM and have a few new Federal SPM in the queue.
4. How much crimp? I am using a heavy crimp.
Thanks in advance for the information and/or opinions.

A classic New-guy mistake to avoid.
Lighter loads are not always better loads. I know its a bit counter-intuitive, but Squibs & fizz-bang loads are caused by too light loads!
My suggestion is find a MAX & a MIN load from a couple of manuals, for the powder & bullet you're using. Now pick the lowest MAX & the Highest MIN & find the mid point between them, & use that for your starting loads.
As you get more experienced & bolder, you can adjust from those to get where you want to go.

My "go-to" loading round for .357 Mag is: Berry's 158gr bullets with IMR4227 17.0gr powder with CCI 550 primers...with a medium crimp. A lighter bullet weight will move faster, but will affect the MOA.
I only use H110 for the big boys, 44Mag, 445SM and others. It is more predictable with the big calibers.
That's my .02
