However, given the data you are using in this scenario, I would consider any of the roundballs at the ranges and velocities in your table to be more ethical than the .243 70 gr at 300 yards.

From what you have said, you seem to have an opinion regarding the maximum range the .243 should be ethically used. I think for everyone, there comes a point, when armed with a .243, that the range of that 12 pt. buck is just two far. Some kind of bell is ringingand we attempt tostalk closer.

I am curious as to where the ethical minimums may lie and what those that use roundballs have determined for themselves should be for themselves. If by chance a minimum kp has agreement, then that is pretty cool, don't you think? I'm not trying to determine whether a .243 at 300 yds is as ethical as .45 RB at 53 yds, though I do agree with you on your opinion of it.
