500 grain soft points Bullet Performance

Uh, Grand Slam?

Yes. It is! Thank you! It's a .375 from the day before. The Lott dug it out of the grass. I was mistaken.

Forrest,
Two things:
1. I thought from your initial description above the photo stated “unknown .458”. That threw me cause I didn’t think Speer made (makes) a Grand Slam in a .458 500gr bullet? Anyway, the “GS” on the base gave it away.
2. Where’s the rest of the bullet?
CEH

@CoElkHunter it met an untimely demise against a 12" gong.

@Forrest Halley
Next time shoot one into something softer and then post the results. Those unforgiving gongs! Ha! Ha!
