Case capacity of the Taylor is minimal. The 416 Rem Mag has always been considered low on case cap and it is a good 10 grains larger than the Taylor. The 416 Ruger is only a couple grains smaller than the Rem Mag and should be a more efficient shape. Would believe lower pressure loads are an advantage in a hot climate especially if dealing with DG.
