So I am thinking about getting another rifle to be my truck gun at least all winter and spring while I am calving out heifers. Going to want cut barrel down to 16.5-18”, and will be using it on coyotes and hogs from up close to probably 400yds. Thinking of 223, 243, or 6.5 creedmoor and wondering which one is going to be affected the least with that barrel length? Thanks
