Good post, wapiti1. Mole hill mountaineering is a good phrase to describe what goes on these days in A LOT of hunters minds because of what they read.
Reality is the best teacher and many hairs are split to the nth degree because of what is read these days vs decades or more of experience.
Choose what shoots best in your rifle, go kill something with four legs.
How many folks have seen writings by Jack O'Connor, Gary Sitton, John Wooters, Ross Seyfried, Wayne Van Zwoll, Craig Boddington, et al? Funny how they managed to kill the animal at such mundane ranges with stone- age rounds like the .270 and the pedestrian projectiles of the day, lol.
And please for heavens sake, don't shorten the barrel and put a suppressor on a 270...
