No not really. I just replace them every 4 years or so. If there 10 bucks apiece its around 2 bucks a year. Big deal and you don`t have to wait for one to break.
I use glass bottles. Contact Jim for more info. skeeljc@gmail.com or visit xxxxxxxxxxxxxx and visit his sight. Good Luck. JT https://www.xxxxxxxxxxxxxx/attachments/20180905_130952-jpg.1516213/
It's always a good idea to give shot bottles the squeeze test occasionally to make sure they aren't getting brittle. It's not a pretty sight when 10 lbs. worth of shot spills on the floor.
