Anyone using this and Varget and Lapua brass running anything over 46 grains? I worked up to try to establish max but we were unable to really get any excessive pressure signs all the way up to 48 gr . No cratered primer strikes, just barely flattend primers, bolt lift was normal, brass looked ok.
I loaded 46.5gr with OAL of 2.910" and not seeing any distinguishable pressure signs? This is the group the load shot at 600 yards

Quoted:
You're using more powder with a 178 than what use for a maximum with 155 grain SMK's. You may be getting away with it because of your OAL" but I would back off some. Load work up is more important than what a book says. Book max loads are not equal to real life in my experience. They don't take oal, throat, chamber dimensions, brass capacity, etc into account. Match shooters nearly as a rule shoot faster than any book load because many of the popular high bc bullets like to go fast. |
