I don't know how the would shoot in the NEF 30-30 but I would try the Barnes X bullets as well. Due to thier design, even the 110 grain X bullet is suggested by Barnes for deer and deer and antelope as is the 130 and 140 grain X bullets. The old 30-30 should get decent velocity from these lighter bullets but the X will do a job on deer like no other lighter bullets can do.
