nchawkeye - YEs, that would be ideal ... experience with both calibers on all species. But I don't think that will be possible. For example, if someone had a bad or marginal experience with a 243 on an elk sized animal, I would hope they did not move up and try a moose.
So, I am more interested in what experiences people have had with these calibers. There is a bunch of hunting experience on this site and even if someone has not pulled the trigger themselves, I am sure they have collectively seen a ton of animals that were taken with these calibers.
