I'm currently working my consistency with an 8" gong at 50yds. I'm just about there, but not quite enough for my comfort in hunting scenarios (the whole reason for the exercise). At 25yards, it wasn't even a challenge. Once I get comfortable with 50yds, I'll be moving the gong out to 100yds.
I shoot my Redhawk with heavy hunting loads (300gr at 1300fps), my 629 with light 44mag loads (260gr at 1100fps), my S&W K22, and my K38 Masterpiece at the gong.
My eventual goal is to replace my rifle with the Redhawk for hunting. It's rare to have more than 100yds between you and the animal, so a rifle is overkill and unwieldy in the mountainous and brushy terrain I hunt. For example, I had a doe walk up on my stand Saturday evening (bucks-only day of course). At her furthest visible range, she was just over 50yds away. She got within 50ft of my stand. That's rock throwin' distance. :)
