Just curious,
Why all the afinity for the 240gr SP? I feel you are missing the boat with some better bullets. Dont get me wrong, they are much better than the lighter weights and any HP from a rifle, for big game. But heavier weight bullets can offer quite a performance increase.
Take the 270 GD from Speer for example. IMHO this is THE hunting bullt for your gun and the velocity/ range its intended for.
You said only 240gr SP shooters, from a rifle I am not such a fan. So I am just kinda throwing this opinion of a heavier bullet out there.
