I started not to admit this but thought new comers to reloading could take note some well earned advice. Mistakes are always lurking when reloading no matter how long you've been at it and being vigilant and not distracted is key words to live by. I almost made the worse mistake I've made last while finishing loading some 45 ACP ammo for the range today. I had sized, primed charged and seated the 230 gr Hornady FMJ's and was starting to get ready to crimp(yep, I do it separately) when I discovered I had used the wrong powder!! My sister had called right about the time I was reaching for what I thought was a pound of Universal Clays and took it over to the reloading bench and while still talking(a no-no) I dumped some in the powder hopper and got off the pone with her. I began to set up the charge weight, 6.2 gr of what I though was U. Clays and proceeded to charge 50 cases. I nearly started the crimp process when I noticed the powder sitting on the bench was not U. Clays but HS-6!! At 6.2 gr, that's not even a starting load for HS-6 so, I would of have at least a very weak load that wouldn't cycle(perhaps) the slide and could have ran into other problems. Now I'm faced with taking all those rounds to the range for disposal or attempting to pull the bullets which I indeed tried to no avail. I have a RCBS Bullet puller than looks like a die with a collet and handle at the top. Going by directions I still had as this is an oldie boughgt many years ago, I couldnt get it to pull the bullets. So, I may have to bite the bullet(nmo pun intended) and take them somewhere to dispose of. It pahys to stop what you're doing if distracted at all and then re-access where you were and double check. Not too bad for a first mistake in 40 years of reloading but still not acceptable.
