Solid bullets....literally - Hornady DGS Rifle Bullets, 45 Caliber, .458, 500 Grain, Full Metal Jacket Round Nose

Dangerous game solids have a relatively easy job: strike a target with sufficient force to penetrate deep and then hold together. A number of dangerous game solids have failed at that over the years, including prior versions of this bullet. The DGS since the early 2000s has been excellent, and has a steel jacket sufficiently thick to render it comparable to a brass or copper monolithic in terms of deformation. This matters a great deal for the .458 WM, where the lower density of copper or brass seriously impacts powder capacity in an already short case. Be advised that the cannelure on this bullet will set a COAL o just over 3.1" in a .458 WM, though in a Mauser action that's magazine length regardless.
