Strange brass -- Flutes on neck

[JB10]

I find a lot of 308 brass like this at a local range. Someone is shooting in the high power match with a rifle that causes it. I still pick it up for just in case brass. I can say it sure takes some effort to resize. Ill use it one day if i need to, but for now its set aside.

Yah, my P7s used to throw the brass more than 20'.

Winner of this sport, IMO, is still the Mini-14. Was walking back to my rifle bench, and something hit the "bench shooting only" sign (10 feet behind the line, 15' from anyone else shooting, and about 9 feet above ground), hard enough that I thought someone shot it. Some guy on the inside rifle lane had a Mini-14; it would throw brass the 20ish feet over the half-fence, and clear another 20' to end up in the creek or canal or whatever it is next to the range. Unfortunately, I think the guy was more accurate with the brass than the bullets.

The HK "Style" chambered .308 rifles are recoil operated NOT GAS and the chamber is fluted like that to facilitate easier extraction. That is also why most of those rifles will not shoot (eject) steel case ammo. I have never tried reloading any of the fired fluted brass, it is throw away for me, unfortunately it makes it where I do not care to fire the rifle often. If I am going to shoot military style these days I take the FN-FAL instead

Yah,
My P7M13 and CZ75B would throw the brass into piles approximately 18"×18". My SR1911 is a close 3rd at ~2×2>
