[QUOTE="AZShooter, post: 1520193, member: 5219"] It appears you had two issues. One is possible irregular shaped chamber and second is a die that may not be sizing the brass enough. If you have any virgin cases left to fire try this: make a mark on case body with permanent marker. Carefully load cartridge with the mark in the vertical position. After firing place that case in same position and see how it chambers. Then rotate it in small increments to compare bolt closure effort. You experienced difficulty placing a round back in chamber without sizing but I am certain you had a random position when you put the case back into the chamber. I'll bet your chamber is not perfectly round or has a low area where brass is flowing causing the difficulty in removing the fired case. You mentioned some scratches on case body. If any brass flowed into low area in chamber removing the fired case would show a shiny area where the irregularity is located. As to fired and sized cases not fitting, you didn't mention if you have experimented with the depth of the die in the press. Have you reached the point where you are slightly camming the die against the shell holder? If you have sized it as much as you can, cover entire case with layout fluid or a sharpie and carefully place in chamber then close bolt. Remove and look for any contact areas. If entire web area is shiny then your die is not sizing the base enough. This is common with some of the thicker brass cases like the RUM. A custom die from someone like Whidden could with that issue. When you get back from work and try some things let us know what you find out. [/QUOTE]
