I only use paper to get zero, and check zero. I practice lots with the Savage bolt gun in .223, 25 gn. of CFE under a 73 gn. ELDM bullet, and if I`m doing my math correctly, a pound produces 280 rounds. As far as targets, last year we had a very bad summer storm that uprooted a large tract of forest 5 miles from the house. Logers went in and cleaned up the mess, but the blown over trees brought rocks up in their root systems. These exposed rocks are super targets, and any misses on my part, are cought in dirt still clinging to the roots. Shooting siting off my bi-pod, I have targets anywhere from 50 out to 550 yrds. I`ve expended a few rounds there.
