This may have come across the forum beforr, but a quick search did not turn it up.
As I was reloading on my Square deal this morning and having to pull the locator pin every time I came across a loose fitting primer, I determined there had to be a better way to get the buttons out than needle nose pliers or tweezers. I opened up my tool box and came across an alligator clip. That was the best discovery I've made all morning, as not only does it grip it well to take it out, you just set it on the bench with the button in it's grip and go about removing the case. When you are ready to replace it, no fumbling to try and get it back in with fingers or other tools as I had in the past. Definitely speeds up the process..
