my favorite rifle is a pre-64 model 70 Winchester, .270. rifle was made in 1947, before i was even born. it's what is called a standard, 24" barrel, steel floor plate, etc. has a leupold variX III, 3.5-10x with a dot reticle. all beat up and scratched from several thousand miles horseback and about a million in the gunrack on my truck. i shoot hornady 140 gr. boattails with 55 grains of hodgdon H4350, winchester magnum primers. use whatever cases i have except resized military '06. the case wall is so heavy on them that is brings the case capacity down far enough it increases the chamber pressure to where it blows out primers and splits cases. don't use this load in your gun. it'll probably blow a primer and stick your bolt. the old winchesters have a fairly long throat and will take a little more powder before they get too dangerous. i still flatten primers pretty good, but i've been shooting it like that for years. bullet comes out at about 3100 fps.
