I too scrounge brass at my local rifle range. Every Fall, we get an influx of shooters whose only purpose is to sight in their rifles in prep for the deer and elk seasons. Hereabouts (Western Washington), they almost universally shoot either .270 or .30-06. Or at least that's the kind of brass they leave behind.
The typical "sighting in" shooter buys two boxes of factory ammo, usually FC or R-P headstamp. They shoot 20 rounds to set or reconfirm their zero and keep the other 20 rounds for the field. I find the empties in the buckets set aside at the range for collecting scrap brass. In that manner, I have more .30-06 cases than I can possibly use and can shoot my Garand without caring where the brass goes.
BTW, many of these once-fired factory cases have severely flattened primers. It appears Federal in particular likes to push the limits when it comes to pressure. - CW
