Have shot numerous deer with a 130gr. Interlock in my 270 with a case full of H4831. Have only recovered two. Terminal performance has been 100% effective every time. One of the bullets I recovered was from my one and only B&C whitetail shot in 91. Shot was high shoulder at about 75 yards. Deer dropped instantly. Bullet was recovered under the hide on the offside. It broke both shoulders and turned the lungs into jelly. It retained 50% of its weight. I have the utmost faith in the Interlock. For a reasonably priced bullet it doesn't get any better. Accuracy is also outstanding.
