[QUOTE="FURMAN, post: 1868816, member: 26535"] Here are the facts. Do what you want with them. The Hornady 300 prc fired case capacity with is ~97 grains H20. ADG 300 PRC non fired is 93.5. The Hornady grew from ~96 to 97 once fired. 30 Noslers are 99(Nosler), 100(bertram), 102(adg). Those are fired in multiple different chambers(not the PRC). I believe Rich said the SI added 2 grains(maybe he posted in here already. I did not read all posts). As Rhovee stated steeper shoulders hide pressure better but it is still there. If everything were magically the same(which is impossible) then physics wins period. The larger case is going to push a bullet faster period. I have seen as much as 50fps difference between two barrels with the exact same load. Same bullet lot, same powder lot, etc... If you want apples to apples the best you can do is case capacity. What we have to decide is when is enough enough. The RUM beats them both. The 30-338Lapua improved beats the rum, etc... [/QUOTE]
