IVe got that gun. the mags are made to "snap" the pellet into the mag... if ya dont, it falls out..... Use the mag correctly and they dont fall out
My issue with accuracy is fliers.... 2 -3 shots will clover leaf at 10yds, then the other two will be off the group some. Ive adjusted the trigger a bit, group size came don a little as its now easier th pull the trigger, but that above behaviour still lingers. havnet had time to do much elase to it
