I am going to purchase a wilson seater from Sinclairs for my 6ppc which isnt here yet? but in their description they list two different seaters for the 6ppc. One simply states 6ppc and the other one states 6ppc oversized. Im not sure which one i need. My gun will be chambered with a .269 neck. Im thinking i need the standard 6ppc and that the oversized one would be for something like the 6ppc-usa. Can someone tell me for sure? Yep I'm ah newbie with lots tah learn?
