Mike, I prefer Federal over Rem brass in 243... Don't know what issues others have had with Federal, but I prefer it.. maybe its just from living near the plant over in Anoka for 15 plus years....

I don't redline Federal brass in my 243s, so I get a fairly long life out of it...

I use mine with confidence.. so maybe you'll have the same luck with yours, that I have with mine,
vs the bad or mediocre luck others have with theirs..
