S&B brass Sellier and Bellot

I've read that this is not very good brass for reloading.  How bad is it?

I have some hxp and ppu but I also have some S&B. Some of the S&B was shot new in my SMLE and some in my No.4.  I did full length size about 20 I shot in my SMLE and then shot it in my No.4 also without incident.  But it worries me.  However, I didn't really want to trash it if I could get a few reloads out of it.  I expect to be building an annealer within the next couple of months but do not have one at the moment.  I do have a broken she!! extractor.  I have a lee die set, as well as a lee collet neck sizing die.

I will also wind up with a little winchester and remington brass once I shoot it the first time.  How are those for reloading.

Thoughts?

S&B problems were non standard primer pockets & hard, brittle brass.

Notice the use of "were".

I've heard some rumors of that not being so anymore, but can't personally verify.

Oh yeah! I forgot about the primer pockets.  When I prepped some of those I'd previously shot in my SMLE for the No.4, the primer pockets were a pain.  Normally when I prep primer pockets, I use a lyman reamer if the primers were crimped and then a lyman pocket uniformer.  If doing more than a few, I unscrew the cutters from the handles and chuck them in my rechargeable drill.  There was no problem doing this with the hxp brass.  But with the S&B, which don't have crimps, I was just going to use the uniformer.  The pockets were tight and shallow and I guess the uniformer would just bite in and grab.  I got several cuts.  So then I went back with the reamer, which helped, but it was still an ordeal to get them done.  But I can soldier on and prep the rest.

The S&B I have were some I bought maybe 2-3 years ago, by the way.

Edit:  The S&B that I have is in the green and yellow box, which looks sort of like the green and yellow Remington core lokt boxes.  It could have been older stock.  It came from a pawn and gun shop and someone had told me they got it from an estate or an older man, I forget which.  The newer S&B boxes are black with a dark forest scene with gold script.
