The guts and the liver, are behind the diaphragm, which is where you shoot deer and then claim the cartridge doesn't work.
You attacked Colorado1135 when he related a lot of experience and then you admitted you'd only shot one deer with a 243 (and shot it too far back at that). And from that sample of one, you declared the 243 wasn't a good deer cartridge.
Says a lot when you have to explain that to another "hunter".
It is irrelevant what you think. What matters is the TRUTH.
