For hunting or SD, does the wider meplat of the LBT style boolits, which iirc, at .280 are ~.035-.050 in. wider than a Keith design semi wadcutter of about the same weight more effective? I know the LBT boolits are said to be very effective, but for those of us who are satisfied with 150-160 gr. boolits at ~ 1,000 fps, is there a practical difference in either accuracy or effectiveness? Is there any advantage to going to the heavier 173 gr. Keith boolit?
