After browsing the site, I'm almost convinced that I will need to turn necks at some stage in my case forming process from .444 Marlin to .260x444 Imp 40°. I'm still deciding on which turner to buy - K&M vs. Forster, but I have seen some gadgets which might solve the thick neck problem I'm running into. In my case forming process, I set the shoulder with a .375 JDJ FL, then neck down with a .308 neck size, then neck down again to .260x444 (I'm using a modified 6.5-06 Ackley Imp 40° die that has been cut down). The problem I'm running into is that the neck becomes so thick during the .308 step that the expander hangs on the upstroke of my press (Dillon 550) so much so that I've ripped the lip off of my shellplate (this happened on the first batch before I annealed the cases, as for the annealed cases, I've actually ripped the neck on the upstroke. As a result, I have to remove the expander to get a smooth return stroke, but I run into the same problem again with the 6.5 die. The hang-up isn't as stiff at this point, but it leaves the neck wavy and thickened on the end. I trim about .020 off the cases to make them workable and have actually gotten decent accuracy with this approach, but end up with a .218 neck length instead of the .220+ of the chamber. I see that Forster offers a "reamer" pilot that will work with my Redding trimmer, would the .308 reaming pilot be an option after necking down without the expander? At what stage do you guys think I should turn the neck? and should I turn twice between stages? My .260x444 chamber is standard to very slighty undersized in the neck so what thickness should the neck wall be? My loaded rounds are between .293 and .294Ø at the neck, which leaves the neck thickness at .015 right? Is this too much?
