I used the 175 LRX last year to "drop" a 585 lb, 7x8 Calif Tule Elk Bull. The bull was ~240 yd away and he moved some just as I shot... hit him at the last rib, missing all vital organs and bone but must have hit a major artery(ies). Shot from a 300 SAUM w/ a muzzle velocity of ~2950 fps from a standing position off shooting sticks. He went down and got up 3 times before staying down. I did get get another shot into his neck during a down period. Not my best shooting... but he didn't travel more than 10 yds.
