Please don't misunderstand what Ron is trying to convey. There is NO way BALLISTICALLY that a .45 PRB is the equal to a .30-30 bullet.
That doesn't mean that hundreds of thousand, if not millions, of deer have not fallen to a .45 cal., or even small diameter PRB over the years. It is not saying that the .45 cal. PRB is not a good choice for taking deer. It simply it has its limitations in how far it will be an effective Killer. That concept relates to how quickly a deer will drop from a solid hit to its vital organs.
One of the advantages of the caliber is its relatively light recoil Not causing shooter to jerk their shot and wound animals with poor shot placement.
The other advantage is the fact that most whitetail deer are shot inside 50 yards in this county, where the 125 grain PRB has enough mass to completely penetrate the chest on a broadside double-lung hit, leaving two, short, blood trails to follow.
But, the .30-30, shooting a 150 grain bullet, has the Ballistics to do the same job at 2-3 times the range. Ron's heavier, Paper Patched, .45 cal bullets, in his rifles, will easily kill deer out to 200 yards and beyond.
His limitation is not the ability of his bullets to be lethal at even twice that distance, but the ballistics limitation of his rifle, AND, his personal choice to limit shots on live game to a shorter distance. He is to be admired for his hunting ethics, as well as his knowledge of his guns, IMHO. :thumbsup: :hatsoff: :hatsoff:
