Remember earlier this week, we talked about dwell time, that fact of physics that combines momentum, recoil, bullet speed and barrel time to affect the way a firearm shoots a particular bullet?
Yeah, dwell time.
The firearm in that example was a new, Uberti Cattleman in .357 magnum that sowed a tendency to shoot 180 grain hardcast handloads a bit high; about 3 inches at 15 yards.
Today, we used the exact same handgun, but we tried 125 grain Winchester fodder.
It's throwing those a little bit low, which tends to support the dwell time experience I've had for most of my gunning career.
I'm betting that 158 grain magnum ammo would shoot close to the point of aim.
