RE: 308 brass for 7mm-08 reloading?
no problem camp, many times I used to make cases from a 308 for a 708 I had years ago. If you get picky youll want a case trimmer and keep everything silky but its not necessary. The only caution is when using military brass (7.62 NATO), it typically isnt as strong or as uniform as the best commercial stuff so keep your loads 1.5-2 grains less than the strongest recommended loads in your manuals.
To make the brass you simply run the 308 case thru the resizing die of your 708. There isnt much difference (.284 vs .308) so you wont need to worry about much reworking like say going from a 308 too a 243,
