Pnolans, just FYI, your .270 and your 7mm have VERY similar ballistic curves. The only difference will be that the 7mm has a bit more energy and it's slightly larger bullet may make it somewhat more suitable for extreme distances, due to better ballistic coefficients and sectional density. Out to 500 yards or so, the difference will be negligible.
