Harder cup HP on game

I've shot a couple of deer with the cup pointed MP 359-640 (167grs) from the 357 using soft 25:1, powder coated and gc bullets before. They apparently expanded and exited, but a buffalo needs the larger bullet to prevent just making it angry. That's why I started wondering about the cup point.

Thanks for sharing.

On my short list of loads to try on deer is this same bullet. I have the no lube groove version that drops 175 grains in my alloy (50-50 WW/pure lead) after powder coating.

I'm hoping for some minor flattening of the nose at the cup, but full weight retention.

I run them from a FA 353 right at 1500 fps.

This is a visual pertaining to the performance of a cup hp bullet in wet newspaper. It expanded more than I expected. These are powder coated .452 bullets fired from a BFR 454 Casull at about 1200 fps into wet newspaper at 12 yards. The large HP was 300 gr, penetrated 10” and retained 162 gr weight. The cup hp weighed 315 gr, penetrated 12” and retained 283 gr weight. I didn’t cast the bullets so don’t know the alloy, but they aren’t what I would consider “hardened”.

If I could get the same performance to scale with the 359-640 I would consider that perfect for my usage!

Thanks for the picture.
