If a 26" barrel limits the 7mm RUM to only 100 to 150 fps more than a 7mmRM then there is not a lot of advantage.
Maybe I would be better off getting a 7mm Rem Mag first, shoot a few Big Sambar with it, at up to say 500 yards and see how the 180 grain Bergers work on them. Then If I am happy with the performance of the Berger bullets at that range, I can then rebarrel later on to 7mm RUM with a longer barrel and extend my range knowing that bullet performance will not be an issue and I can also get the higher velocity available via a longer barrel.
What do you think of this logic?
