[QUOTE="Edd, post: 1166145, member: 30592"] A 7mm RUM case is larger than a 28 Nosler. So by definition that should make it more powerful. I doubt there will be much real difference between the two with normal, 24"-26", barrel lengths. You are limited on how much gas you can flow thru a hole at a certain pressure. If you look at all the existing load data it appears those limits on a 7mm start somewhere around 7mm STW capacity. The case capacity of a 28 Nosler is practically identical to a 7 STW. [/QUOTE]
