I've had one ordered in 700 SPS varmint since last winter, and am finally going to get it. I expect it will be here next week sometime, and I'm really anxious to get started with it. Now I've gotta get all the reloading components rounded up which will be fun also. I'm very interested in how it's going to shoot for me.
I'll bet there are others on here who have been tinkering with the 17 Fireball already, and can give some experiences.
