James B: I would just have to see it to believe it. I refuse to believe that given equivalent hits a .243 is less deadly than a .30-30. I suspect that the problems you've seen have simply been poor hits with the .243 versus good hits with the .30-30.A marginal hit with a .30-30 is not going to magically be more deadly than an identical marginal hit with a .243. The .243 has virtually identical energy at the muzzle and substantially more energy at 100 yards than a .30-30, and that 65 thousandths of an inch more diameter isn't a significant increase in "margin for error".
