bsa, I initially tried them in my .375 AI, but found(IMO) that penetration suffered in close range shots. I think that with the increased velocity they expanded quickly and violently, losing approx. 35% of their original weight. They had picture perfect mushrooms,and did not have core/cup seperation (presumably due to the interlock). But, with early expansion and weight loss,they lost sectional density and then penetration suffered. Great on the "perfect" broadside shot, but I don't always get those! I wouldn't hesitate to continue using them in my H&H, but in my AI it's Barnes only. memtb
