From White's link.

"For hunting animals up to elk size, 160 grains FFg Black Powder is accurate with the same ball and patch and is a potent load at short range, up to 100 yards. Ignition with FFFFg in the pan of the Egg lock on the rifle is virtually instantaneous. It’s quick enough that an experienced shooter can unfailingly call his shots."

Seriously, 160 gr? In what rifle?
