Today I started Load development for my .300 win mag and 185gr Berger Hunting VLD bullets in my Blaser R93 .300 win mag match barrel. I have done the pressure test today with the following results:

77gr-915m/s
77,5-923
78-926
78,5-940
79-946
79,5-956
80-964

At 79,5gr I could see pressure signs on the primer... Now I have loaded 3 groups of 5 rounds with different seating depths for the Berger seating depth test with 78 gr of powder.
