knowing Cabalas, I tend to completely disregard most anything the have to with firearms. the .280 should do an honest 200+fps faster than the 7-08 and maybe more.
A quick scan of the Hornaday manual (not exactly my favorite) shows the 7-08 using a 139 grain bullet hitting the 2900fps mark using a 24" barrel. But a further investigation tells me that the two 2900fps loads were with ball powders, and the rest are in the 2700-2800fps range. Now you move up to the 7x57 with the same bullet, but with a 22" barrel. They are showing 2700fps. This round seems close, but maybe 150fps short of max. The next step is the .280 of course. They used a 22" barrel, so you can add 100fps to their readings right away with a 24" barrel. A 26" barrel will add some more. In the manual we see 2900fps and 3000fps loads with the 22" barrel length. The max pressure for the .280 is 60Kpsi (?!!!) which is kinda funny when you look around. The max for a 25-06 is 63K psi and the .270 is 65K psi. Once again I have to put the "swami" bunch out on the other side of left field!
Yet the max for the .308 based cases are 60K psi.
Taking these figures a step further we know the case capacity of the 30-06 case to be much greater than the .308 based case family. Yet they all started out in life as a 7.92x57 Mauser, and were either shortened or stretched a little bit. We're not talking about a piece of brass made in 1921! The 7x57 Mauser will take 60K psi just like the .280 or 7-08 contrary to what the "swami" says. A fine example of their insite is the 6mm Remington being spec'd at 65K psi, while the 7x57 is held much lower. In a Remington 700 it would easily hit the 63K mark with zero problems! Same could be said for the 280 Remington in spades. The .280 will make better use of a 26" barrel than the 7-08 from charge weights alone.
I imagine old Bob is rolling over in his grave over these crazy specs
