gman,
You're right, Some nice accurate .45 Colt loads at about 950 fps - 1,000 fps with some of my 240 gr. - 310 gr. bullets ( I have about 7 different moulds in that weight and cal. range ) will take care of a white tail at 30 - 50 yards.
I've shot a few " full tilt 454 Casull " loads............NO FUN ! !
