Hi I am with you Geezer. You seem to be speaking of experience and ethics, and I agree. Here long shots are stuff of legend our terrain is rugged. From my experience, shortest shot deer was 9 or 10 feet, longest shot 60 yards. Most were taken with 303. I putter with reduced loads in winter, no idea the velocity but I know with certainty they will be lethal upto 50 yards, they shred thick books and peirce frozen spruce 6" in diameter. Will I use them to take deer I dought it. I will stick to what I know for now. I plan to work up a deer hunting load a bit more to learn and trial. Why, because I know. I know what it is like to look for wounded deer. I know what it feels like. Never again.
Be well
