If you dont think there is a difference in between a 243 and a 25-06 something is wrong.
Who said otherwise?
BTW, I am starting to notice a trend here. Seems like most folks who feel the 243 is marginal are from states with larger deer. I will admit that if I were hunting in Colorado or North Dakota I would prefer something with a bit more bullet. However, in the swamps and thickets where I hunt a 150 yard shot is considered long and a 75 yard shot is average so the 243 does the job well.
