I run a little test becuse I was told that the JSG would change POI when left in high humidity, this guy said a matter of hours, so I left it loaded for four days. I loaded 3 JSG Sticks in my Omega with a Nosler 300 grain PP... this load was producing around 2 1/2" groups at 100 yards. Not great, but plenty accurate enough. After the four days I went to the range and shot... missed the bull by about two inches. What ever I would have shot at would be dead!
