Mike,
They are loading their own brand of bullets at this time.

• DGS™ (Dangerous Game Solid) bullet features a blunt nose profile and a super tough alloy core to penetrate deeply through hide, muscle and bone.

• DGX™ (Dangerous Game eXpanding) bullet expands up to 1.25 times the original diameter, and its tough alloy core resists deformation at all velocities.
Yes I realise grafs and outhers are discounting them. This is what factorey list is.
Mike do you have a sorce for Hornady? They should be able to get them.
