The thought hit me:Has anyone sized jacketed pistol bullets down a smidgen?
Yeppers. Done that. I sized some .312s through a .308 Lee bullet sizer die to use them in a .30-30. They actually come out .309 but that's better that .312. I have a TC contender barrel but haven't tested them yet. That was a last winter project, or maybe the previous winter project, that I haven't quite gotten around to.
Regarding the .350 Legend, the velocity that Hodgdon's site claims for a 147 grain 9mm XTP has me interested in one for winter jackrabbit blasting. I shot some with a Marlin .357 lever action and 158s at about 1700 or so .. bunny blew up leaving a hair (hare? :)) cloud drifting in the wind. A 147 at 2400 or so seems even more diabolically interesting.
