Knew it would be arguable
That ball is 175gr but at .490 I look at it as being pre-expanded. The soft lead also mushrooms well all while staying together.
I do admit to being overly optimistic in my first post as I was used to seeing the patched ball work in the rifle with velocitys a tad over 1,850fps.
I still think the pistol w/60gr is somewhat more powerful than a .357 but equivalent to a ??
Range is a big factor as there is nothing worse than a ball unless it would be a cube.
I should have limited my statement to 60yds or under. I look at my rifle as being a 100yd weapon.
