It is a tamed down 17 Remington, few years ago I rechambered a 17 HMR to 17 Remington, it worked well, but I could never get it to shoot without vertical stringing. I sold it and bought a Savage 10 and rebarreled it to 17 Remington, it is great. You could get one of the 17 Handi barrels and do the same thing to 17 Fireball, it would be a great experment, and would not cost a lot to try. I am hot on the trail of a .14 barrel I want to put on a stubbed off Handi barrel, that could be fun. Larry
