Ordered .223 cases not knowing that some have crimped primers in them. After snapping my RCBS decapping pins and expander assembly, I thought I'd look for one at US Reloading Supplies. Low and behold they had the perfect decapper assembly. This one does not bend at all. Did 75 cases so far and no problems at all. if your having the same trouble I was having, give USRS a call, you'll be glad you did. Three taps with the hammer and their out. Call now. It's a great company!!
