Need input from the Brain Trust that resides here! I have opportunities to hunt everything up to Elk-sized game - typically 150 to 400 meters. But - I have a problem! Due to injuries - and 2 subsequent shoulder operations - I can't take the pounding of a magnum caliber the way I used to - even my 30-06 is a butt-whipping on the range. I DO love shooting my 6.5x55 - loaded to factory specs - so something of that load or maybe a little more is what I'm looking for... Looking for the ideal caliber that will allow me to hunt the distances I enjoy, shoot more than 5 rounds at the range without whining, and reload my own. Am I looking at a flat hot round in the 6.5 range? Help this busted-up guy out! I know there's no "ideal caliber" and the question could be argued for years - but I need someplace to start.
