The laws of physics positively states that all things being equal you would have the same exact amount of killing power. However the two equations that are not equal in this equation is bullet weight and diameter. The equality argument can be made for each existing caliber directly under the next however at some point you realize that you've talked yourself all the way down to a 22 long rifle or maybe even the 22 short. This is the point where the realization finally sets in the you have indeed been slowly talking yourself down. Is the 7 mm slightly less than the 30 cal? Yes, slightly! With that being said I personally prefer the 7 x 57 mouser. For me it is the perfect ballance of range, recoil, shot placement, etc. Shot placement I believe is the deadliest equation of all!
