.25 pellets to try FX Streamline

I believe the .25 streamline was designed around the JSB 25.4gr? I personally haven't tried it yet, but its been on my list. I've used the JSB 33.95 mk2, but they do suffer a bit in the speed/drop off department. Still hit plenty hard though, i have mine sighted to 40m with a point blank range of around 45m. I've also had good success with the Baracuda Hunter 27.47gr on medium power for pest birds. Baracuda Hunter Extremes were a mixed bag for me, sometimes they shot great, but were inconsistent in my barrel
