I pulled my .50 barrel off today in preparation for installing the Pac-Nor .45 barrel. I discovered that the Fed 209a primer will seat COMPLETELY in the breech plug.It is snug with no slop but this is the first time I have encountered this and for headspacing purposes should I bevel the leading edge of this plug so as not to recieve a false sense of being "home". My concern here is that it will feel right but actually bottom out on the leading edge of a cock-eyed primer and not actually be seated properly.......

Rick, I'd bevel the BP for no other reason than to ensure a good primer feed; in most cases the primer is "hanging" downward from the bolt face and the bevel sort of guides it in the plug.

My concern here is that it will feel right but actually bottom out on the leading edge of a cock-eyed primer and not actually be seated properly....... Here's what I do, maybe you'd have a better way. Adjust the depth of the primer without regard to the edge or not. Then take a primer and put some clay or something slightly sticky on the primer, chewed gum might do, but .... ya know. If the spacing is done right the clay will show the primer depth on the side of the primer because the plug will push it back as far as it is in the cavity. If by some chance you spaced on the primer end no part of the clay will be scrapped away. Also it will act as a gauge and you'll know exactly how far the primer is fitting into the plug. |

Rick as I was looking for clay today,and to no avail, I had a brainstorm! Dangerous I know.. ;D but this one actually worked very well.I decided to use "Whte Out".It dries very quickly and you could easily see the line. I got it right the first time BTW... ;D
