I bought a ton of the Hornady steel case training ammo, probably... 8-10 years ago now? Great stuff. Shoots like match ammo. Priced like blasting ammo.
Only downside is if your rifle doesn't like steel case. When I got it I had an Armalite M15 that was brilliantly accurate; but it didn't like Wolf. I figured the Hornady being better quality than cheap Russian stuff would run even if it was steel cased; but no luck. I even tried both the lacquer-coated and powder-coated version of Hornady steel cased.
