Brass: Lapua - weight sorted and trimmed to 2.010"
Powder: 46.8 grains Varget

Seat bullet 0.015" off lands, needs to be checked every 500 rounds due to throat erosion.

These won't fit a magazine and aren't what you're looking for but you asked for accurate load specifics

Edit: Don't try this at home. This load is hot and may cause damage to a standard rifle
