Oh I agree the 6mm AI would be a great choice as well...and certainly out performs all the other mentioned options. Especially in a long action rifle.
I will say this though...I have not had any problems with my WSSM brass needing to be annealed (buy mine is a 25..not the 243) and I have not had any difficulty in locating brass...and the 25 WSSM is far less popular than the 243 or 223 WSSM's.
