I was going to say if length restrictions are going to be present a 300 norma mag improved is about the best setup you’re going to get. Could have defensive edge + P the throat and pickup some more velocity. Apples to oranges but most improved version run the 230 3030+FPS. +P and you should be equal with the 245. If length isn’t an issue then it opens up a few more options previously mentioned already.
My standard Norma has a 28" barrel and sends the 230's at 3060 with N570 and zero pressure signs. A Norma Imp or +P would surely be faster.
