Thread: 7 PRC Wild Data

Doing some research so I can reload for cousins new Tikka 7PRC.
Looking at the Duley articles written on the cartridge and comparing it to data from Hornady, for the two powders I’m going to try, Duleys have used 5 grains over book max Hornady data for 162 gr projectile.

What’s going on there? Have Hornady gone ultra conservative with their data. Seems crazy. I’m used to seeing people state 1-2 grains over book max but 5 grains doesn’t seem right.
