I made a promise to my grandson to take him shooting every weekend from when the snow leaves until the snow returns. We go to a couple of hravel pits on Federal Land up in the Cascade Mountains. Every weekend we pick up any brass other people left behind. Our best weekend was twenty-two pounds of brass. We have enough 223 brass to last the rest of my life and several years into his.
He has a AR15 that he shoots every weekend. I only let him shoot fifty rounds a week sometimes a hundred.
I have a Remington 700 with the bull barrel in 223 and a Ruger 77/223 stainless boatail synthetic stock.
I lay a tarp out to catch the brass from the AR15.
I also mark the end of the cases with a red permanent marker so we can keep our reloaded brass seperate from any range brass we happen to get mixed in with our reloaded brass.
We just plink for fun most of the time, but I don't let him go cowboy. The deal it to take your time, aim at what you are shooting at and hit what you aim at.
I also have the fifty round plastic ammo boxes with the hindged top and have them market for each gun and what is inside & what bullets are loaded in them as well so the brass pretty much stays together for each gun when we take more then one 223 out shooting.
As pieces of brass become lost or garbage I just grab another from my prepped brass load with the old used stuff and color the end red.
I don't look at head stamps any more. After shooting it gets resized, put threw the trimmer. Tumbled if needed then loaded & crimped.
I have three tupperware like containers that are 3 1/4" by 7 1/4" by 11" full of prepped 223 and about 5 gallons of cleaned, deprimed and swagged primer pockets ready to get resized if my smaller prepped brass gets low.
