Caliber Conversion for a Dillon XL650 Progressive Reloader from .223 to .308

Caliber Conversion for a Dillon XL650 Progressive Reloader

The following is a summarized account of converting a Dillon XL 650 Progressive Reloader from a Small Rifle Primer (SRP) in a .223 Remington, to a Large Rifle Primer (LRP) setup for a .308 Winchester. As always, the first thing you should do is ensure the XL 650 is empty of cartridges, powder, and primers (however if not steps will be provided to include their removal). If at any time you require detailed descriptions on a specific stage, consult your Dillon Owner’s Manual. Also consider when performing a complete caliber conversion, you may want to clean and/or lubricate all the necessary parts being removed or replaced as it provides a perfect opportunity to get inside all the components.

    Your set up looks great. Thanks for the motivation to do a little tidying up this weekend. (I wouldn’t be willing to post a pic of our press right now.)
