I have a few thousand rounds of empty .223 & 5.56 brass, and I am going to start loading for a Stevens model 200 , Mini 14's and an AR15 Bushmaster. My plan was to sort threw the brass and pick one kind to use for the Stevens for varmint accuracy with 53g hollowpoints, and use all of the rest with 55g fmj as plinker rounds for the auto's. I have all sorts of brass, mostly range found stuff. What is a good brand to use that is a commercially produced ammo ( I don't want to buy any more brass). Remington? Winchester? Does it matter?
