I shot a nice mulie buck two years ago with the 150 gr Interbond in my .30-06 at about 175 yards or so (broadside lung shot). I wasn't sure where my first shot hit him so I shot him again for good luck :wink:
Both bullets were complete pass throughs and there wasn't much meat damage. They shot ok groups, about 1.5 inchs or so for 3 shots, but not great (Remington 700). I've heard others talk about really bad accuracy in the .277 weights, it kind of makes you wonder if the first ones had some sort of defect. :?:
I wasn't completely happy with the accuracy out of my rifle, but didn't really take any time to tinker with them. I did do some expansion testing into phone books (not exactly scientific), and they held together well. I'd consider using them again, but I'm using a different rifle this year.
