[QUOTE="grit, post: 632877, member: 4112"] I'll be happy to explain my thinking, such as it is :D. The difference in maximum velocity is around 100 fps for these cartridges. When I compare cartridges I look at where they go sub sonic. All else being equal, this clearly illustrates the difference in maximum effective range. We shoot the same 300 grain hybrid in either case. These rounds go subsonic at 2700 and 2825 in typical conditions where I hunt. This means to me, both rounds are effective way beyond a mile, way past a point where a 125 yard difference matters in the slightest. What makes the Norma really attractive to me is it achieves this in a standard length repeater with a 26" barrel. This means a nice 12-13lb field ready rig. For the Lapua, you want a tac338 or similar and a 30" barrel. That's a 16 + strictly long range rig and doesn't fit my style of hunting well. I hunt BIG, rugged country. Another consideration is efficiency. I'm pulling numbers off the top of my head, but the Lapua takes approximately 10% more powder to achieve 1% more velocity. Personally, I'll take the more compact rig, better barrel life, and less recoil over the 100 fps. [/QUOTE]
