When, I was much younger, I too, wanted, to shoot a big Magnum Rifle, across Canyons at Elk and built, a custom .338 Win Mag on, a lapped, squared, Wby MKV action, w/ a 25 1/2" Douglas Premium Barrel, Glass Bedded, trig work, etc. The Rifle "Clover leafed" 210 Nosler Part's and 225 gr Horn Spire pt's ! I never did get to shoot one, across a big Canyon ! It was, a "Killer" tho,.. on BOTH, ends ( Pre muzzle Brake era!) I sold it, for two Grand, when I started Bow Hunting and soon realized, how deadly, a sharp 3 bladed Arrow thru, the Heart/ Lung area was and decided that, a "reasonably good" Bullet, would "do" the SAME thing, if it Mushroomed and penetrated "well"! Thus, I went back to the 7mm R Mag ( 154 gr InterBond's at, 3,070 FPS ) and recently, to a 24" Tikka @ 7.5 pounds in .270 WSM, driving the wonderful, 140 grain AccuBond's at, 3,150 FPS, that's still going OVER 2,000 FPS at 750 yd's. Nosler says that, the AB will expand down to 1,800 FPS,.. IF, I ever needed to shoot, that far!
