Do solid copper bullets destroy gongs?

Speed is probably the key to making divits in AR 500 steel ...the 17 Remington at 4800 fps with a tiny 15.5 gr copper bullet was tryed once to see if it would... it did, with only 15.5 grs. left a nice digit in the AR 500. Should try the 50BMG with Armor piercing...but I didn't want to mess up the AR 500 steel for science...but it does penetrate alot of mild steel with 265 gr of US 869.
A true AP bullet, not a penetrator, copper, etc. will penetrate. I one ran a .30 165 black tip AP at 3500 in 300RUM and it went right through half inch AR 500 at 100yds. Found the stripped jacket and the tungsten core is probably still going.
 
Someone put 6 deep pock marks with big "pimples" on the back side and and 1 pass through on my 600 yard 3/8ths ar500. What can you do??

4x,

Did the same with some noname 142s at an estimated 3200 f/s. Slowed them down for use in competition. Saw similar results @ 1k with a 7mm RSAUM. Velocity over 3k, but don't remember by how much.

No. Speed does. 2600fps on 1/2 in. ar500 is lead or copper paint. Unlimited target life. 2800 you can feel with your fingernail. 3600 leaves an ugly crater that will ricochet bullets back to the shooter. I leave that one at 500+. Excessive but safe.
 
BTW, keep an eye on the fire starting potential during the dry seasons too.

Copper solids start fires better than anything else I have seen. If there is dry tinder near the targets, keep a fire extinguisher nearby.
