What's the thought on using range pickup 223 cases with unknown number of reloads for 300blk. I try to only use once fired range pickups for 223/556 reloads.

One nice thing about 300blk, it is easy to see the case web on the inside.

As long as the primer pockets are good and tight, it's g2g. Subs have a good bit lower pressure than a standard 223 round, so you can get good brass life if you anneal before forming. Supers have higher pressures, but still lower than 5.56 IIRC. All my federal brass gets turned into 300 blk, as do cases with split necks and/or screw-ups I make on the press when doing 223.

Just note that some brands have too thick case walls and necks can be too large with a seated bullet. Necks with a seated bullet should be .334" or less. Here's a list of cases to watch out for:http://www.300blktalk.com/forum/viewtopic.php?f=141&t=82732
It is easy to inspect the 300 BLK cases as you can easily see the inside and inspect for stretching and possible problems.
