i use the interlock and interbond quite a bit. I shot a large mule deer buck this last Thursday, at 365 yards, with a 270 Winchester, using the 140 gr BTSP. The buck was way uphill from me, facing downhill. I shot him thru the front shoulder, low in the shoulder. The bullet went thru the leg, blew a hole through a couple of ribs, went through the heart, penetrated the diaphragm, and then lodged in the liver. I recovered only part of the jacket, which weighed 28.5 grains. The buck fell downhill about 15 yards and then collapsed and expired. The bullet did it's job, but did come all apart during the process. I'll post a pic later on.
Sounds like maybe you should have been using your 7mm instead
