J. J. Perodeau (580-237-7388), formerly of Marcel Thys in Liege, does a lot of DR work in the US, and sees a lot of messed up barrels. I spoke to him recently about one that he speculated may have had A-Square or similar ammo run through it.

Holland recommends the Woodleigh, and that's the only solid they use. It's the one that I use. Hornady is currently bringing back it's previous solid design, which is a gilding metal covered steel jacket design very similar to the Woodleigh. Since that bullet will also soon be available in the DR diameters and weights that I use, I will also be using it.

The 480 and 500 grain Woodleighs would be fine in a .458.
