Keechi Kid,
Sorry, your first post seemed to suggest something like a precise correlation between grains of bullet and pounds of big game.
I've used Partitions for over 40 years now, on big game up to 1500 pounds, but haven't found that magic grain weight yet, partly because velocity seems to modify the equation considerably, I would guess due to the front core disintegrating more violently at higher speeds. Have used Partitions at muzzle velocities up to 3300 fps, and find speed increases their "killing power" more than bullet weight--and even more than speed increases killing power of monolithics, the reason I suspect the results involve the front core.
