I currently carry a Ruger Hawkeye predator in 223rem. It is my truck and kicking around gun but I might replace it with the Ruger Compact laminate in same caliber. Both rifles are a one in nine twist. There is the possability also that I might just have the barrel cut down to 21" on the Ruger Predator. My shots are limited to 250 yards and ninty percent of those are 150 or less. I want a good load for mt lion and coyotes. Not sure if I should go with 60gr partitions or something along the lines of a 70gr sierra. What would you use or load for this application.
