Anecdotal only since i don't use Barnes bullets but a friend who posts here does (maybe he will chime in).
He's killed a few hundred head of African game and one time over he shot the 145 LRX against a 300 Win Mag loaded with 200 gr Partitions. Says the 145 LRX from a 7RM penetrated just as far,did as much damage and killed about as well as the 200 gr Partition.
Kind of surprised me too but that was the report.....
Point being that construction trumps weight, and that tired old bromide called "SD", which means essentially "nothing".
