You crack me up, 500grains! Samuel Baker did not 'merely shoot pigs' with his, either!

Permit me to quote Graeme Wright, who relates the experiences of many of us who HAVE hunted after the advent of 'effective' calibres (with your kind indulgence, of course):

"In Australia, paradox guns are regularly used and show just how powerful and effective they can be. Using solids these guns are capable of taking buffalo. Typically, at ranges of about 30 yards, a side shot at a buffalo's chest will give complete penetration with the projectile found against the hide on the other side."
