I'm always amused to see people put 8.4 grn or even 7.9 pellets in these blowback guns and then complain that they are hitting low.
Try 7 grn match wadcutters or the non lead pe!lets they are probably tested with by the designers.
The original Umarex semiautos didn't have blow back and were able to average something in the 350fps range.
To expect the same from a gun that syphon half of its CO2 off to work the slide is wishful thinking.
Of course blowback pellet guns are underpowered compared to their bb equlvalents. Steel bbs weigh only about 4 grns.
Alloy pellets are fine for 10m plinking.
