I started getting the new style plastic bottles a while back after finishing off tin can style from the day. Anyone have opinions on whether there is any longevity difference with powder in plastic bottles? I assume its probably too soon to know. Also not sure how long it has been since you guys had the metal style, with our local powders it was relatively recent the change to plastic bottles. I worry about all sorts of things long term, whether the heat here might degrade the plastic over the years, or cause chemicals to leech into the contents etc. I wouldnt think gunpowder companies would risk hangfires and misfires with degrading powders down the track though.
