Hello folks I am about to start reloading .45ACP with a Hornady LNL progressive loader and after seeing all the pics of firearms destroyed by double-charged or squib rounds I will not even start without a powder check die. -I know the Hornady Powder cop die is a simple and effective die. -I have seen a you tube video of sombody who mounted a Dillon powder check die with the audible alarm. That sounds like the best option but this guy was drilling into the frame of the reloader and I don't want to that just to install it -I have heard good things about the RCBS lockout die as well which is what I'm leaning towards These are the three dies I know about for powder check. If there are other, better ones please share. Thanks!!!
