FWIW I bought a subscription to load data last night and so far I am not really impressed
The above loads are for the Speer bullet specifically and is rather tame because of the soft lead and lube used in those bullets. If hard cast and better lubed they can be turned up a notch. 6.5 grains will put you right at that 1100 FPS number with a hard cast bullet.
save 2400 for hotter stuff.
here's 6.5gr win231 . . .
My load for 158 grain 357 is 6.5 grains Unique. It's a lot of fun in my model 19 S&W. Snappy.
The Speer reloading manual gives the max charge as 6.0 grains Unique for a velocity of 1034 fps. Their starting load is 5.5 grains Unique for a velocity of 970 fps.
It is my standard 357 Mag load these days. I’m not into many full power loads these days. In fact, the last full power 357 Mag ammunition I loaded up were in 2005 and I still have a few boxes left.
What charge powder and how do you know it's "about 1000 fps from a 4" revolver?"
I tend to not give out my powder chsrges for safety reasons.
I have a chronograph to measure the the speed of my ammunition.
For what action and barrel length? In a 6" revolver, of the powders listed, I prefer Unique, HS6 and 2400. I like to check the powder and bullet maker's recommendations against Lyman's published hard-cast data. They usually concur and when they don't, I avoid that powder/bullet combination. In this case, it will also really help if you have a chrony.
I personally use 2400 when looking for that velocity range, and in fact in my Model 19, that is my velocity range. I have settled on 13 grains with 158 SWCs. In my 4" guns that generally puts me right about 1200 FPS.
