[QUOTE="Stgraves260, post: 1908038, member: 19988"] See if this helps. It takes roughly 1000 lbs of kinetic energy to break the shoulder of a elk. So what I suggest is this. If you have a ballistic program device see what caliber rifle gives you that energy at distance. I use JBM in my smart phone. My 260 Remington has 1000 lbs of kinetic energy at 850 yards at 1150 feet above sea level. My 140 grain Berger’s are still traveling at 1800 FPS. Berger say there bullets still need to travel 1300 FPS for them to expand. Now i took a cow elk just shy of 900 yards in Colorado. I was about 8000 feet above sea level so youR rifle carries its velocity much further. My 260 still had just over 1200 ft lbs of kinetic energy and around 1950 FPS. I took that elk home and fed my family all year. Yes my little old 260 Remington did break the shoulder. I found fragments in the heart and the lungs. It looked like it hit the opposite shoulder and stopped. I was able to retrieve the bullet. It did not have complete pass through. I have used the JBM program sense the first gen I-phone. It has never let me down. I really hope this helps. Good luck. [/QUOTE]
