Ordered 200 cases once fired .308 Win from Midway a few months back and just getting around to working with it. The brass is all Lake City ,98 thru 05. I've always heard that surplus brass has thicker walls etc. and less case capacity so I decided to weigh the water volume capacity of a few different headstamps that I had on hand. The results are as follows:
Brass empty wt. full wt. water wt.
LC 04 177.7 233.6 55.9 gr.
Hirtenberger (HP) 170.9 227.0 56.1 gr.
Cavim 91 180.6 235.6 55.0 gr.
Frontier 171.1 226.9 55.8 gr.
Federal (FC) 181.3 236.9 55.6 gr.
Rem. (RP) 173.4 229.3 55.9 gr.
Win. nickel 171.0 227.1 56.1 gr.
W-W Super 158.6 216.8 58.2 gr.
With the exception of the Cavim 91 and WW Super all cases are within .2-.3 gr. and the RP case capacity is the same as the LC case. Most of my .308 reloading has been with RP and FC brass with no trouble. With these results is it really necessary that I start with 10% reduced loads. Please fill me in on your thoughts, tests, practices along these lines. Thanks.
