I recently picked up a box of 270 140 grain accubonds and have been researching published loads. I plan on starting with Ramshot Hunter and stumbled across something I thought interesting.
In Noslers loading data book, they have a max powder charge of 56.5 with a MV of 2971.
Ramshot's loading data has a max powder charge of 53.7 with a MV of 2999. Both seemed to have 24" barrels used in their test. I guess what caught my attention is 3 grains difference on the max loads seem pretty significant.
Anyone have ideas on the variance between Nosler and Ramshot? Both using the same bullet, powder, and barrel length?
