I recently read an article in a magazine that described the differences between 7.62 and .308 rounds which I already understand. The other thing the author mentioned is the difference in headspace which is more concerning. He mentioned that a gas gun chambered for 7.62 would be especially hard on .308 brass because of the headspace difference. It makes sense logically, but since there are a lot of semi-auto owners on this board, I wanted to get real world opinion.
I have an SR-25 that has shot .308 better out of it than 7.62 so I stuck with .308. I also have a GAP-10 on order, along with a F&D FD308 and a JP LRP07. I've collected my own brass comprised of FGMM (7.62 and .308). I'm new to reloading, but I plan on using Varget and 175gr SMK along with these cases.
Question: Should I separate the different brass and reload them in different batches to compare the data or would they be similar enough not to matter?
Question: Will any of my current and future gas guns be especially harder on the .308 cases, than the 7.62 cases?
With .308 cases and match rounds more readily available, I'd like to shoot that exclusively in all my AR-10 format rifles. I only shoot 600yd and 800yd target at the moment, knowing full well I'll eventually go custom bolt gun when I want to go further but I really enjoy shooting the EBR's at the moment.
I would like any first hand advice from gas gun owners on which rounds they prefer and what I can expect by using both cases for my reloads? I have RCBS equipment and will use a FL die to resize. Thanks in advance.
