Greetings again @AngusM,
If you have been shooting factory loads for a while hopefully you have been saving your brass. If so it might be a good time to have a count up. Lee Loaders size the case from the outside but do not expand the neck. For this reason the lighter cases like Winchester are easier to load in a Lee Loader. You definitely do not want to load mixed head stamp brass as neck tension will vary widely. I would suggest getting a hand primer as well as I find the idea of seating the primer with a hammer terrifying. I neck sized brass for my .308 rifles for decades using a neck sizing die in a press but currently size my .303 cases in a Lee Loader with good results. It would be best to get someone to take you through the process to start with and explain what is happening at each step. The instructions and videos leave a lot out.
Regards Grandpamac.
