i have a 50cal...and i cant get it to shoot conicals either. ive shot powerbelts, tc maxi hunters and the other maxis..., and 2 diffrent buffallo ballets. cant get good enough accuracy to be satisfied...but that thing is a round ball tack driver....so i quit wasting time and money with conicals...i stick with PRBs now. mine is also 1:48 after i too checked lol. it loves roundballs for some reason.
