I have a 300wsm and 2 325 wsm. I also have a 223 WSSM (that doesnt feed well). I have been able to come across a little brass now and then. I just got some 7mm wsm brass and 284 brass (dont have either rifle, but would keep the brass for the future). My brother has several 270 wsm and loves them. I would like to get a 7m wsm some time, but it doesnt do anything a good 7mm rem mag wont do.
