When i was a kid, i sounded just like zrexpilot, now 30 something years later, and putting a couple hundred animials in the freezer later, it has changed the way i look at things. Especially since i've had the chance to hunt "all sizes" of animials in Alaska, Canada and some of the lower 48 states.

I still have the origional 700 Rem. in .243 Win. cal. i bought in "about" 1970, but i don't hunt deer with it any longer.. It's pretty much shot out now, although it is still accurate enough to hunt deer with. (i still have other .243 Win.'s too)

Once i started useing something a bit better, it didn't take long to see that i probable wouldn't be going back to a .243 Win. for a deer rifle, even though i did build a 240 Wby. years later and give that a try too.. (that i also still have)

Keep in mind i "never" say 6mm's won't kill a deer, but i do say most everything bigger works a "lot" better, and like James said, it's because of the "bullet" not the velocity...

Sometimes sh1t happens, and haveing the edge of that "better" bullet (in this case, a larger diameter bullet) will save you a lot of grief!!

Like i said in an above post, i go by what my "experence" has shown me over the years, not by what a piece of paper says it's "supose to" work like..
