I load for 12 of my 18 Bobs and have always used standard, not +P, Winchester/Olin brass. My shots are typically under 300 yards and both the 100 grain Partition and 110 grain AB shoot good groups and produce quick kills. The weakest actions in my service are a Savage 99 and a pre-WW1 Swedish military 1896. I load these a little lighter than the 1898 style Mausers, both large and small rings actions, and the commercial actions from Marlin, Remington, Ruger, Savage, and Winchester.
Unless the chamber in your rifle is over-size, I wouldn't worry about using good quality standard brass in lieu of +P brass with the maximum recommended loads.
