I just finshed loading and shooting some low-level loads using 230rn lead,and for my short-range needs they were great.Since they have no crimp groove I backed off on the roll-crimp die and just squzzzed 'em 'till they lookd right.
this way I could load em longer than normal for less bullet jump,and it improved accuracy in my sloppy-chambered Ubeti s.a.
