We have had a string of nice weather recently, so it was time to go to the range. When looking through the brass buckets it's all 9mm. There was a few 45acp, some 40S&W but I noticed some 45 had small primers. So I left those as well. I think folks are shooting 9mm due to availability and cost. I hope it changes this spring and summer! I have a lifetime supply of what I need. But after decades of collecting brass I can't help myself...
