Hornady says it's a deer cartridge with their 123 grain SST bullet. 1193 ft-lbs at 300 yards isn't horrible. Drops 8.7" with a 200 yard zero though. Then like a brick past 300 just like most cartridges.
Lots of discussion of the assorted forums. Most saying it's a deer sized game and varmint cartridge.
Likely has more to do with how accurate it is out of your AR. Minute of Deer is 2 to 3 inch groups at 100. Consistency is more important than group size.
