Big Bore Al
Go to this thread from Jayson/ DoubleZranch:
375 RUM and the 260 Accubond...
Nosler AccuBond 260gr is the leading candidate right now in 3/8" bore. G1 BC is 0.473.
My Savage in 375 Ruger has a Factory Special Order 26" tube and with Hodgdon's max load with WW760 of 79.5gr and a Fed #215 primer the Chronograph says 3022fps Av w/ SD of 9fps. The 375 Rum should go 3100fps+ with this bullet in a 26" tube.
Long Live the 3/8" Bore LR Shooters!!!
