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
I have 35+ years of chrono data in my notebook, and the cartridge that seems the least affected by barrel length is the 7mm-08.
Back in the 80's in two different articles in different gun rags the authors sawed off 7mm-08 bbls in one and two inch increments. I believe they chose the 7mm-08 randomly, rather than by design, but both rifles showed surprisingly small loss of velocity as the bbl was cut shorter.
