You should be fine, I use the Lee Universal decapping die as well. I would recommend you get a couple of extra pins, for just in case. I have broke a couple over the years, and nothing pisses me off more that to have to stop and wait a week for a $.99 replacement part. So I tend to keep a couple just so I can keep going while I wait for a replacement.
I think I have broke 2 pins and I have done 5K+ milsurp .223 and 30.06, and countless others. It is a good item
