Need advice on max 7 x 57 Mauser, 140 gr loads

[strangwn]

I am looking for ideas on max loads for strong, modern rifles, such as a Ruger #1 in 7 x 57 Mauser using primarily Nosler 140 gr Accubond, or equivalent, bullets for deer/black bear hunting. I may also decide to use 150 or 160 gr. I want to approach the limits for this rifle/cartridge combination.

with the 140'a i like rl-19 in the 50-53 gr range 52.3 grs gives me 2880,in rem brass.
and 2750 in +p roberts brass in my wifes shorter bbled rifle with 51 grs.
h-414 is used by many to get outstanding results also.
