Re: explosive .243 round
As Darren said, the 75's run faster. I shot a lot of 75's and some 87's from my 6mm-223. They are both excellent, the 243 has the capacity for either, but if you want EXPLODING birds, look at the little 58 or 65 Vmax's....
I've dusted some birds and squirrels with 65's fom the 6-223 adn they're simply awesome, from a 243 I can only imagine how it would work. Post pics of the smear that's left when you try them

I hear crazy things about those, but like i said, never shot em. what size of bird are you lookin to pop? barn swallows? pigeon? chicken? turkey? </div></div>
I run the V-Gren's from my 204 Ruger in 26gr trim, and they turn eggs into a mist, the residue that's left on the stump is cooked eggwhite, enough energy is imparted to the albumen that it turns white.
Accurate enough (1/2ish inch @ 100y) and 4500 fps MV's
