I t must just be that reading the ballistics of the NE 450's by candle light makes them look better than the current 458 Win numbers...Not to berate the double cartridges, they are wonderful, just trying to figure out why Hornady is the only major ammo supplier to be able to produce 458 ammo at 2150fps and why more folks don;t take a look at what can be done now with great powders and even better bullets in that cartridge...
