Thanks guys
I may have just over thought the question. I was looking at it like this, the .22 mag is .22 caliber. A .223 by definition is only .003 larger than the .22. My thinking (thanks to the Jack Daniels) was that they were to close in caliber to be of much difference but obviously the .223 is a much stronger load given the fact it is over 1000 fps faster at the mussle tham the .22 mag.
I guess I was just wondering which you wold choose if you had to pick one. Looks like a .223 is still the best bet.
