I run the 230gr hybrid in my 300wsm, i get a 2665fps average from the 24" barrel of my htr, loaded to mag length with h4831. Realistically how much gain would you get from seating out? 100-150fps? Maybe? I would try doing some load development first, you may find your accuracy node is near the velocity you would get from the shorter mag anyways.
My groups are hovering around 1/2moa for horizontal and 1/4moa vertical, so I have no complaints.
