Sorry, just re read your last message & you said TDR mags.
T R Robb himself, says he doesn't think pellet size makes much difference to accuracy, unless they are so undersized they don't engage the rifling properly. The sizer does make pellets more uniform though, & that's where he believes the accuracy improvement comes from. Probably using quality pellets of a uniform weight helps too.
