I killed two bulls with 140g old style ballistic tips, 100-175 yard shots. I know the Barnes are a sure fire winner:
65-66g of IMR 4350, Rem case, Rem 9 1/2, bullet jumping .050 off the lands, expect 3200-3250 fps depending on the barrel and small groups with the tipped tripple shocks.
160g Partitions with 61g of IMR 4350 is also a hammer of Thor.
Our parties over the years also killed a lot of bulls with the 154g Hornady sp with 73g of R#25 and win mag primer at 3200 fps, small groups with small Standard deviation.
