I seem to have misplaced my new Lyman manual

[:@], could someone tell me what they list as a MAX load for a 160gr bullet with Reloader 22.
I shot some handloads today using:
72.5 and 73.0 grains of R22 and a 160 gr Nosler accubonds and they were shooting just under 1". Nosler data shows 73.0 gr as max, but there was no sign of getting close to high pressure. I am sure I can add more powder and still be safe.
