[QUOTE="Trnelson, post: 1528882, member: 42308"] I’ve been down that rabbit hole with WC867 years ago. Trying to use different charges to maintain a velocity window as temperatures changed. It was a larger change in velocity as temperatures changed. My load would fall out of the accuracy window if it was too cold or worse yet spike into unsafe pressures if it was too warm. The same load that shot 3,220 at 30• would stick the bolt and blow the primer right out of the case if you tried to fire it at 90•. That was an embarrassing mistake that I was fortunate enough to get through with just a trip to the gunsmith and not the emergency room. I had loads worked up for every 10• change with a temperature written on the case, worse yet I had to carry a selection of them while I hunted and try to plan ahead as to what I would need to have. Eventually, as better powders entered the market I went to them. Looking back it seems crazy, but it’s what a lot of us did some variation of to maintain suitable accuracy. [/QUOTE]
