Finally did my first reloading of a 270 win 130nbt. My question is? How do I know if my powder is any good? I bought Reloader 19 and 22 11-12 years ago when I thought I would start loading. I live in a very dry and hot area. The powder has always been in my garage unopened in a cabinet. When I went to shoot today my chronograph was all over the place. Nothing consistent or even close to each other. Is my powder bad or primers after being in my garage for all those years? Chronograph is new and I loaded with the RCBS link.
