I have an ample supply of .300BO brass, but am going to help a newbie ease into reloading. I have a ton of .223 brass, so I am going to venture into make several hundred rounds of it into .300bo brass. I have a harbor freight chop saw, which jig/gauge have you fellers used that is the best to use. Also from what I understand, once you trim it, you need to chamfer/deburr, then run into a .300 sizing die, then you are good to load? I am also swaging the primer pockets first. All replies appreciated.,
