Thread: 7mm Rem Mag with Sierra 168gr

@7mmsaum thanks mate the 7mm Mag always seems to have a huge inconsistency between loading info available. It is one of the most inconsistent rounds when it comes to chamber dimensions as well. This rifle with the factor barrel always showed low velocities for the load always coppered the barrel very badly but with a good hand load shot very accurately with 0.25" 5 shot groups common. I am up at the AKL NZDA range on Sunday and will make a start.
