Peace Brother! I am me and you are you and personal liberty with your guns are yours. I am into what I need and nothing more. But in time I will try full-blown 500 Smith and Wesson MAGNUM with a 525 grain wide-nose gas-check bullet at upwards of 1500 fps at the muzzle.
That is 500 Maximum territory with a straight .500 caliber bullet versus the .511 caliber of the 500 Maximum. But a 440 grain at 1350 fps ought to suffice for a pig.
