Reply To: CROSSMAN PREMIER MORE CONSISTANT THAN JSB EXACT?
The 15.89’s are around 19.8 fpe and the 14.3 are around 20 fpe. (if your velocities are correct) So let’s use 20 as your fpe. If you are looking to get closer to 880-900 fps you probably want one tin of lighter pellets to try. 13.4’s could be good (820 fps). 10.3’s might wind up moving too fast (930 fps)
