I bought them a thousand at a time 6-7 years ago. Same with .22 LR. Just tossed a couple bricks in the cart every time I went to Cabelas or such. I remember when Ammoman had Lake City green tip 5.56 ammo for less than $200 a thousand. I was buying it just for the brass. I stopped when the floor joists started creaking.
One used to get a better ROI on reloading. But I got into it so I could tune the load to the gun. And its still a great hobby and a really good skill to have. Think about taking it up.
Best,

Did the same with .22LR’s - well the family did - have about four thousand rounds. I have a Gammo Nitro in .22 and it’s a hoot to shoot. I can get all the .22 pellets I want at Wally’s - five hundred rounds for $8 ... thing shoots out at 1200fps.
