cr500,

You need to match the bullet you use to the

1. Gun / Cartridge Chambering
2. Game being shot
3. Impact velocity on game.

As oldsarge says,
"Nothing wrong with the bullet in its proper case"

You need a bullet that will withstand very high IMPACT velocities
for when you shoot game up close with the 300 Weatherby otherwise
you get the result you got.
