Natchez shooters supply is selling brand new LC 09 .223 cases for $119.00 per 1000. They are the best deal going.
They take a little prep to be perfect, but at that price, for new brass, it's hard to beat.
Range brass can be good to worn out, plus you are getting all differet brands made from different lots even if they are the same brand.
If you care about accuracy, you want to start with new cases from the same lot, properly prepare them and then keep track of how many times they have been reloaded by you. I retire my cases after 8 reloadings. keep them for SHTF use.
I load for accuracy, if you just want to shoot, range brass will be fine as long as you inspect it for problems from being old or defective or shot with loads that were way too hot and damaged the case.
One bad case can blow up your rifle and hurt you or others. To me, it's just not worth it.
I have picked up range brass for my 45, but only after talking with the shooter. Many shoot new ammo and don't save their brass. If I know it's just once fired, I take it, but I don't take just any rounds that I find, especially rifle brass that goes in rifles that generate high pressures.
Just my 2 cents, John K
