Re: SPS Tactical or Standard SPS?
I have an SPS 26" heavy barrel .17 Fireball. Very accurate gun but a pain to carry around. It's barrel-heavy so I literally have to sling it upside down just to carry it over my shoulder. I use it for sit and shoot groundhog hunting and carry an Encore in .223 or .17 Fireball for run-and-gun hunting. I think you'd get the best of both worlds with this caliber in the 20" tactical. It's compact, lighter, and you'll lose little in velocity and, I'll bet, nothing in accuracy. I'm generalizing here but I think I'm correct in saying that shorter and heavier barrels tend to be more accurate because of their stiffness and less of a harmonics effect on the bullet going down the barrel.
The older I get, the stronger gravity becomes.
