Well if the revolver is for defense and you are going to carry it by all means you should practice some with full house .357's that you are going to use. When I use a revolver I practice a lot with .38's but the last 10 or 12rds I shoot what I am carrying for defense. I have shot this caliber most of my life and I still enjoy it. So far as the ammo you are looking at I never have shot any as I roll my own. I see where it is rated at 1050fps. A good +P+ will turn those numbers. Good luck.
