I have a lot of 100 Hornady cases I bought to try. I have loaded them and fired them 5 times as of today and they just won't shoot well. I have tried everything I can think of and no luck. Shot about 80 rounds today and had OK groups not great. Took out some factory Blackhills 175's shot a decent group. Tried some Blackhills brass I reloaded around a year ago, same lot of powder primers and bullets. One of the loads I shot in the Hornady brass, 1 hole in the paper and I was tired and NOT doing my part. I get better velocity and much better SD and groups with LC and BH. Anybody else have bad luck with Hornady brass? I think I may just order 100 Lapua and get it over with. My LC and BH has been great but it will not last forever. Wanna kill these ads? We can help!
