This is what I did. I have a lot of military brass just sittin' around, no caliber designation. The 308 idea came from some where in my head. Anyway.
I took some 30-06 and sized them down to 308, without the expander plug and decapper in the sizer die, since I didn't know what was going to happen. I did this very slowly and carefully since this was my first attempt at this. I ended up with this very long neck. WOW was the least of what I thought. I then went to the trimmers and what a pain to try and trim so much. So to get the neck to within an 8th of an inch of case OAL, I used a very small pipe cutter to cut off about 3/8" of brass off, which appeared to shrink the inside neck diameter a wee bit, due to the pressure of the cutter I guess, the pilot on the trimmer didn't fit. I then ran this brass, with the 308 expander from the size die set in a universal decapping die, since at the time I wasn't sure of total neck outside diameter and didn't want anything to get stuck in my 308 size die. I then trimmed down to correct length and ran each through a case gauge and then measured everything out and now I have 100 or so 308 brass. I was surprised that the neck didn't need turning with using the mil brass. What an exercise that was a cool learning experience and fun. I plan to now do 22-250, 243, 250 & 300 Savage and maybe 25-06 just for fun. I have these rifles so this brass I will use to reload, maybe sell the commercial brass. I will use my single and dual Herter's and Rock Chucker for these.
