It all boils down to how fast do you want (need) to push a bullet and of what caliber ??
How fast do you need to have the bullet going,at what distance ??
All this talk about the "magical" 1000yds kinda makes me laugh. Talking 1300,1400,etc,etc. makes me laugh out loud. This . . UNLESS . . we're just talking punching paper for the fun of it.
Hunting - - -> How will any given bullets terminal performance be at the farther ranges. How about at "just/only" 600yds not to mention 1000yds+. Will it have the energy of a 22mag ?? Will it penetrate and expand like a M855 ??
Then we have the laws of deminishing returns. IOW . . overbore chamberings and felt recoil. The PRC's come to mind. As does the 6.5-300Wby,26Nosler,and some other of the "new and better" chamberings. A good "whack" on the shoulder and a quickly burned out barrel is worth . . . what ?? --- SAWMAN
