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
First off -- I don't have a prejudice toward/against any of the cartridges you mention.
Secondly - hogs out to 400 yds, I'd think you'd need punch and bigger holes.
Thirdly - Denton or Mathman etc. could explain this better than I. The larger the bore (caliber) the less velocity (speed) is lost by shorter barrel length.
Example of the principle - I had a 20" bll 308 W, yet I was able to get the same velocity w/ 150 gr bullets AS with 22"ers.
Bore Capacity can only be increased so much by added bll length >> to a point. In converse, a larger bore is less susceptible to velocity loss in
shorter lengths. HELP Denton <grin>
So, if you follow me, the 6.5 or even 7-08 will fair well in shorter barrel lengths.
Good Luck
