What's your favorite .357 Mag. target load.

[375supermag]

Hi...
My general purpose/target load is currently a commercial cast coated 158gr LSWC over 8.5gr of Blue Dot. IIRC it clocks out at about 1100fps.
Shoots well in all of my and my son's .357Mag revolvers.

Question:

So I had never loaded for 357 mag, and I see a lot of the pistol powder I have, but what about Berry's copper plated bullets? Are they essentially the same as Extreme bullets? Do Extreme bullets have a velocity cap to them?

My favorite pistol powder is Alliant Power Pistol. Does anybody have a load using Power Pistol?
