I purchased a box of range brass ( 45 acp ) from Wes and it is about 90% S & B. I googled it and got lots of mixed reviews. Some said junk, some said really good. One thing that was brought up a few times was the fact it was hard to deprime and then reprime because the pocket was a little too small. I deprimed on my 550 B and there were a few that were a little tougher than others but when I reprimed it went in just like I like my primers; snug and tight. Anyone here have much experience with these cases. They look great. Like once fired for most of them. Thanks
