[QUOTE="GrayCreed, post: 2200864, member: 114633"] I'm pretty sure you could look at 6.5 x55 data in the Hogdon book and scale up I think the 6.5x55 is 59g of H2O where 6.5prc is 62g of H2O. While that is 3 whole grains that is only a 5% increase from the 6.5x55. also keep in mind the 6.5x55 is a lower presure round than the 6.5prc. if you look at the Hogdon 270win data it has 4451 I would stay clear of the max 270 load for 160 bullets for comparison to 6.5prc (case capacity is more for 270). Or you could give me that 4451 and I give you a pound of 7977 [/QUOTE]
