The first Nilgai bull was shot with a 335 gr Clearwater Custom bullet..they called them Rhino Penetrators. They were RN and if you listen to "the experts" they were all wrong...1 shot from my Competitor 50 AE, and I dropped it..1 and done...the second Nilgai bull was shot with a 340 gr Woodleigh Protected Point Weldcore...1 shot...the bull ran a bit on a mad dash death run, but collapsed and was out...another 1 shot kill...bullet placement as always is very critical
