JG the 120gr was originally a thin jacketed hunting bullet like the 140gr but the sillouhette boys couldn't knock down the targets(metal goats,chikens, hogs)with it as it was so they beefed it up. So now instead of a progression of thin,thicker,thickest you have thick,thin.thickest jacket progression. That's the main reason for the hunting popularity of the 120's...especially in 280's. powdr
