went out with the advent of the Nosler Partition, and the BAR. The African game laws wont LET hunters use autos, guys don't want to waste $15,000 on a double rifle, so they settle for a .458 bolt action, and HOPE that the extra power will do the job(as vs fast followup hits on the head). Just because THEY are limited by laws, does NOT make the .458 bolt OR the double rifle a better bet than a 308 autorifle. Nobody practices enough with double rifle ammo costs being what they are, 308 is 15c a shot for practice ammo. The recoil of 458 means you are twice as slow for a followup shot as you'd be with a 308 auto, especially with a BOSS compensator. The BAR is also available in 338 and 300 Win Mag. you aint GOT a "boy" to lug around your 15 lb double rifle, even if you do have such a rifle. Any of the above listed auto rifle calibers is a LOT more versatile than the 458 or the double rifle is, too, because of its far better performance against gravity and wind. I rate such rifles with shotguns, as pcs I'd never bother to own, or recommend to anyone, for any sort of serious use at all.
