Yes, the original SAAMI pressure limits for the Bob was 53 or 54 K PSI. There is a +P rated pressure limit of 58 K PSI, but that is still mild compared to modern cartridges which are typically in the 62-65 K PSI max avg pressure limit.

No reason not to push handloads in the Bob above 60 K in a modern rifle.
