[QUOTE="BrentM, post: 3014200, member: 61747"] Good point. What people don't think about is terminal performance of high sectional density bullets. There is a reason that number is printed on bullet boxes etc. High sectional density is a key factor in terminal performance. Add in a bullet that is designed for penetrating heavy tissue and bone and you have a potential recipe for success. A 6.5 really tops out at 150-160 class bullet and generally around 3000 fps. That combo is only going to yield a certain amount of potential of energy, basically kinetic energy. Mass and speed. Most people believe the more mass and speed the better, which is generally correct, but the mass and speed also needs sectional density. I feel all this is beyond most peoples ability to deal with so they just spout out things like, well its good for deer, but you need a 20mm for an elk..... [/QUOTE]
