375WSM. My data was acquired in a 26" barrel Savage with an Adams & Bennett barrel. Converted Federal 300 brass and 215 primers.
270 gr. Hornady Spire Point: 64.5 gr. AA2520@2632 & 67 gr. RL15@ 2711
260gr Accubond: 68gr RL15@ 2750, 67gr AA2520@2770, 67gr AA4064@2769, 68gr AA4350@2700,& 69gr IMR4320@2876.
225 Hornady Spire point: 67gr AA4064@ 2954, 71gr. RL15@2996, 68gr AA2520@3053, & 68gr AA2460@3036. I would consider these to be near max loads with the listed components. Different brass and primers and of course, rifle could change things. Please start low and work your way up. Hopes this helps.
