I think you are right Tex , lot to lot seems to be pretty varied in R22. I have always tried to get the same Lot# in any powder I used, but one time ( back during the Great Bill Clinton Primer Scare) I had to use different Lots. I didn't get any pressure signs ( 300 WM) but my 76gr/180 XBT group had to be re zeroed about an inch horizontally. When I was playing with the .224 TTH I bought a 5# jug. I still have some left I'll use. I did get some R23 and R26 to try. Here in Utah, its rare for it to get below 10deg during the Fall hunt ( say a storm comes in) but the late season antlerless hunts ( Nov-early Feb) can be pretty rank, though seldom below zero, usually single digits. Merry Christmas guys!
