I wouldn't be too down on that performance. It killed your buff with one shot and you said it shoots well in your rifle

. In fact you have two projectiles there tearing up your quarry.

After 40 years of hunting I prefer my projectiles to 'come apart' in-side the animal. An animal can't breath or do much if its chest is full of blood. IMO I think a lot of this 'full penetration and maximum weight retention that is necessary for a projectile to be successful' is only a current fad supported by certain manufacturers.

Thank you for posting.
