I have shot them and i even have some left... When I first started shooting the .458's it was the first bullet I tried. It shot very well from my A&H. But, as with just about any Hornady I shoot into wet clay - it would strip the lead out of the copper. But, I will be the first to tell you wet clay is not an animal + I already had previous bad experiance with shooting a 220 grain Hornady Round Nose from my 300 win mag and finding the copper just under the hide on the entrance side of an elk - and more than once. So my mind was made up along time ago.
The "interlock" is not a bonded bullet - the interlock is suppose to hold it together but often does not - especially when shooting it at the upper end of it's velocity rating.
