Charlie, Nothing special really. I am set up for them and have a pile of wads,etc. I load them several way's and use them in all my 16 gauge gun's. A lot of guys like the cheddite hulls like Winchester,RST etc. and every once in a while I splurge and buy a flat of RST's. I think there is no better but reloading is still cheaper and I enjoy it.
Thanks to a couple of generous PGCA members I have a supply on the way. We really do have a bunch of great guy's here.....
