These are the best bullets on the market for the 357 magnum. I use them out of a 6" Ruger GP100 and in a few days, an 1892 16" barrel carbine. I'm getting 1500 fps out of the revolver and expect more out of the carbine, maybe 1700 fps. They're super accurate and the hardest hitting bullet you can buy for a 357 magnum. It's my go-to for anything that might need a little extra thump.
