[QUOTE="El Matavenados, post: 1388907, member: 89192"] The man in the big brown truck brought some more goodies today. Just little stuff like cartridge boxes, and Lee case holders. But the best thing was the set of Hornady 300 SAUM dies. My brother and I took the full length sizer and chucked it into a drill, and went after it with the Dremel, grinding it down a bunch (in order to set back the shoulders on my Norma cases). Well, since the die was ready to go, why not take it for a spin??? I trimmed a case down, lubed it up, and we carefully adjusted ithe die until it was setting the shoulder back .084", per Elkaholic's instructions. Easy peasy! Well, if you're going to do one, you might as well keep going, right??!? So I did all 21 cases. 21, you say? Why the odd number? Well, it seems that when someone counted out the casings, they miscounted. Bank error in my favor, collect 1 free casing. The mouth on one was a little dinged up, so maybe they just threw in an extra to make up for it. After trimming and sizing, you can't even tell. I intend to ream the necks out using my mill and a reamer purchased for the occasion, once it arrives. Once that's done, I'll be a hop, skip, and a jump away from being able to load up some fireforming loads. Of course, the fireforming will have to wait until I get the rifle built.... As I pondered the best way to ream the necks, there were several routes I could have taken. But I decided to go with my mill, which required me to make a special fixture, which required me to get some extra tooling. I thought I would also do the outside neck turning at the same time as the reaming, but that would have required another $125 of tools, so I'll just do that in a separate setup. [/QUOTE]
