The load quoted in the OP seems excessive to me. If you fire really hot loads a lot, you need a heavy gun.
But a .357 isn't really meant as a range gun. It's for moderate use in defense or hunting. Routine heavy .357 use will eventually cause wear, sooner in a smaller gun. Frequent .357 use in LE guns caused the introduction of the L-frames and GP-100.
Light bullet, high velocity ammo is worst..
When I was a gun writer, I had access to gun and ammo engineers and PR people that the public doesn't. They ALL agreed with what I'm posting here.
