I wish I had an interlock bullet I perfectly placed in a Gemsbuck, but it ran off with it in the boiler room, and after tracking for 1 & 1/2 days was lost! (had a perfect stone benchrest situation, rifle rested on my hand on my hat atop the rock) One interlock was retrieved from my Hartebeast, shot at 80 yards, which shed the jacket and was found in the shape of a teardrop--not my idea of a confidence inspiring result. Both were utilized in Hornady Light Magnum ammo which I thought at the time was a good idea...no longer. Buy better IMHO, tho either of your choices are absolutely acceptable for whitetails
