Ya that would be a good use - but why would you use such a heavy projectile for gongs?
Because i got them for $25 for 500 and a high SD bullet has a bit less wind drift.

When/If i start shooting BP silhouette at the STL BR shooters club i need a bullet that will knock over the rams too. They have strict rules on what type of bullets are allowed so you dont damage them. Lehighs or any non lead solid are a BIG NO NO.
The penetration is amazing though.
1) Water jug
2) A soaked compressed phone book
3) Over an inch of particle board
4) Through another wet phone book
4 And roughly 3" into a hard tree stump
Nice wound channel too...not great but nice.
I havent been able to retrieve one yet. A bull elk is probably an exaggeration but i wouldnt be surprised if it did.
