I guess I'm pretty much a one trick pony when it comes to 17's. My choice has always been the 17 Remington teamed with Hornady 25 grain HP's and IMR-4320. It is a combination that has worked really well for me and I just never changed. Of course when I bought my first one the internet was in it's infancy, there were two readily available 17 caliber bullets, both 25 grain. One was sporatic in its performance and the Hornady was always consistent in its performance.
I would echo John's advice though for extended shooting sessions. The Fireball would probably serve the purpose well and you wouldn't have to deal with the vicious recoil of the 17 Remington.
