[QUOTE="AJ Peacock, post: 220303, member: 4885"] I thought that the 338-378WBY was less than 100fps faster than the 338-300RUM at the same pressure levels? But the Wby needs more powder, a larger boltface and larger magazine for the extra/same fps? Quickload shows the WBY tops out at around 2850fps with the 300SMK and a 28" barrel. It shows the 338-300RUM topping out around 2800fps for the same barrel/bullet. Maybe I mis-remember? AJ [/QUOTE]
