[QUOTE="Lee7588, post: 2940672, member: 123764"] None of my books show pressure. Here are a few screen shots from nosler comparing 150 gr bullets and if comparing same powder imr 4895 with roughly the same powder charge 40 - 40.5 the speed goes to 7mm-08 not the larger bore. 7mm-08 with a charge of 40 gr is achieving 2750, 308 with 40.5 gr is achieving 2544. Bigger piston or bullet isn't showing higher speeds. I think if I'm understanding your stance correctly the 308 should be out performing the 7mm-08. [/QUOTE]
