Finally had time to do a little testing, I set it up for shooting sparrows at 30 feet +- so shooting over the Pro Chrono for 16 shots Hi-466 L-451 using a Aim Sport red/green dot sight set on green got it sighted in, started at 30mpa end 28mpa so I'm looking at 8.7fpe with the JSB 18.1gr Exact Jumbo Heavy it should be killer on those sparrows. It was hot outside so I setup in the garage it worked pretty good.
