RE: .243 for deer
The Swede does not use the same case as the 243. The 260 does however. The 264 has bullets 60 percent or so heavier than the 243 and there is really no comparison when it comes to bullets. I have had about equal performance with the 223 and 243 on deer. Both have got the job done when bullet placement was exact and conditions perfect. Between the two since both are legal in our state, I could flip a coin between the two and expect to accomplish the same thing. HOWEVER, The 6.5 is head and shoulders way above both of them.
