[QUOTE="BountyHunter, post: 1112518, member: 12"] Most tight necked guns are marked on the side of the barrel what the neck is IF they are really tight necked. Before you jump to that conclusion, will a loaded factory round fit in the chamber? If yes, then not tight neck and you have a problem with the modified case not fitting your chamber which would not be unusual. If the loaded round will not then you have issues to try and determine what the neck diameter actually is. Your smith can do a cerrosafe cast as long as they follow the instructions exactly. What caliber are you talking about anyway. If you know the neck, then you can have someone else turn on case, use a dremel to cut a slot down the neck and then just seat a bullet long. Take the firing pin out of the bolt and just slowly chamber the bullet and pull out slowly. Measure the marks on the bullet. Chances are they will be from .030 to .050 and go from there. You can use a candle to soot the bullet or use a black magic marker to make the marks easier to see. If you have a magazine gun, your COAL is limited by your mag so start and max mag length and go backwards. [/QUOTE]
