[QUOTE="Deleted member 46119, post: 1016764"] Nothing wrong with RCBS. I have RCBS and Redding for the RUM based chamberings I load for and shoot.I have a 650 and would not resize RUMs on it. Too much flex in the base plate. IMO You will break it before you can bump the shoulder. What I believe after reading this far is that: You have a wide, short chamber. Not a bad thing but... When you resize you are reducing the diameter of the case but the shoulder is "moving" up. Think squeezing a balloon. Which is a great metaphor for cases anyway. In many ways then are balloons with a cork in them...... so You are not bumping the shoulder back far enough. IMO you will break your Dillon if you try. IIWM: [LIST] [*]Get a single state press to resize the RUM brass in. Something fairly strong. Get the Recommended RCBS shell holder, it's on the box and I think its a #38 but could be a #4. [*] Get a Hornady headspace comparator. Measure a fired case that will rechamber nicely, on the shoulder per the instructions, then measure a sized case. Adjust your die until the sized case is .001 to .003 shorter. [/LIST] You can keep using the Dillon for the remainder of the reloading process just without the sizing die. When I use my Dillon for rifle reloading, I do this or similar: [LIST] [*]Clean the brass. [*]Resize without the expander ball. [*]Clean off lube. [*]Use the Dillon to complete the reloading process. Instead of a resize die in the first position, a neck expander die. The rest is the same. [/LIST] [/QUOTE]
